摘要： PURPOSE:To send a data without error by forming a couple of pulse signals having a same pulse width narrower than both pulse width of unipolar pulse modulation signals, synthesizing a couple of the pulse signals to obtain a bipolar pulse modulation signal. CONSTITUTION:A unipolar pulse modulation signal S1 whose level is inverted from each bit and whose pulse width differs in response to the logic level is supplied to pulse generation circuits 2, 4 and a couple of pulse signals S2, S3 phase locked at the leading and trailing edges and having a same pulse width narrower than both the pulse widths of the unipolar pulse modulation signal are formed. Then a synthesis circuit 5 synthesizes a couple of the pulse signals S2, S3 to form a bipolar pulse modulation signal, that is, a bipolar signal. Since no DC component is included in the bipolar signal, an error in the data transmission is prevented.

摘要： PURPOSE: To eliminate transmission disturbance due to noise by applying FM modulation to a luminance signal and a synchronizing signal by a carrier wave including a high frequency signal, converting conversely a chrominance signal and a chrominance synchronizing signal into a signal occupying a low frequency band and applying FM modulation to a sound signal into a signal of an intermediate frequency.
CONSTITUTION: A Y/C separation circuit 1 consists of low and high pass filters 2, 3 and separates a video signal into a luminance signal and a chrominance carrier wave signal. The luminance signal and the synchronizing signal from the filter 2 are modulated by an FM modulation circuit 4 by using a high frequency as a carrier wave. The chrominance carrier wave signal and the chrominance synchronizing signal from the filter 3 are subject to low frequency conversion by a low frequency conversion circuit 5. A sound signal is subject to FM modulation by FM modulation circuit 6. These signals are superimposed by a superimposing device 10 via high pass filters 7, 8, 9 and converted into an optical signal by an optical output device 11. A photoelectric converter 12 of the receiver receives an optical signal and separates the luminance signal, the sound signal and the low frequency conversion chrominance signal via extracting filters 13, 15. The separated signals are demodulated by demodulation circuits 16, 17, 19 of the next stage.

摘要： PURPOSE:To prevent the radio interference to adjacent homes or rooms and the wiretap by performing the communication between a telephone set body and a handset with brightness-modulated infrared rays and adopting frequency division or/and wavelength division. CONSTITUTION:A circuit equipment A is provided in the telephone set body side, and a circuit equipment B is provided in the handset side. In the equipment A, a light emitting part 6 radiates brightness-modulated infrared rays. A light receiving part 7 receives brightness-modulted infrared rays radiated from the handset side and converts them to an original electric signal of modulation. A demodulating circuit 10 demodulates this modulated electric signal to convert it to a voice signal, and this voice signal is transmitted to a telephone line through a balancing network 1. In the equipment B, a receiving part of the handset receives radiated modulation infrared rays and onverts them to a voice signal to generate voice from a receiver 17, for example, a speaker. Meanwhile, voice applied to a transmitter 18, for example, a microphone is modulated by a modulating circuit 22. Since the carrier frequency is changed to f1 and f2 between the transmission from the telephone set body to the handset and the transmission from the handset to the telephone set body, bidirectional calls are secured.

摘要： PURPOSE:To maintain a good receiving state at all times even in case of an optical signal received from any direction, by placing plural photodetectors so that the half-power angles coincide with each other, and constituting so that the composite directional pattern becomes nearly circular. CONSTITUTION:Plural photodetectors, for instance, SiPIN photodiodes 23-25 are used, and they are placed and combined so as to become like a triangle when seeing from the almost upper face. As for the directional pattern of photodetecting sensitivity in this case, the diode 23, the diode 24 and the diode 25 become like a full line (a), a full line (b) and a full line (c), respectively, and when these respective directivity are synthesized against a photodetecting point P, a nearly circular synthesized directivity is obtained as shown by a broken line (d). That is to say, a directivity of 360 deg. is obtained against incident light. In this way, for instance, even if a head is moved by 360 deg. in a state that a wireless head phone is put on, a good receiving state can be maintained at all times.

摘要： PURPOSE:To attain modulation and demodulation of a digital data signal easily, by providing a word synchronous signal having a pulse width being >=1.5 times of a bit period at each word and a parity data of at least one-bit. CONSTITUTION:The word synchronous signal having a pulse width being >=1.5 times the bit period T, by inhibiting the inversion at two edge positions of bits within two-bit range of the word synchronous signal part S. As to the parity data, the selection is done so that ''Os'' are an even number including the 2-bit data of the part S. The data is fixed depending whether the polarity of the front edge of the start of each word goes upward or downward, by selecting even number of data ''Os'' in one-word. Thus, the modulation/demodulation of the digital data signal is done easily, the circuit constitution is simple and the polarity of the word synchronous signal is unchanged, allowing to attain high timing accuracy of the edge (arrow) for reference phase determination.

摘要： PURPOSE:To reduce errors in data transmission and to decrease the transmission time, by providing a humming correction code and a parity bit to data to be transmitted in a specific method. CONSTITUTION:In storing data of 16 bits to an RAM of 4-bit unit, for example, data D1-D11 in order to bits of the RAM except a parity p are humming correction codes H0-H3 and the H0-H3 and O and obtained and added. In obtaining the H0 first, the bit test for D1, D2, D4, D5, D7, D9, D11 is done in accordance with the A and an even parity is obtained by adding the H0. Similarly, the H1, H2, H3 are obtained in accordance with the B,C,D. The parity of P is obtained by taking the bits of D1-D11, H0-H3, and P as an even number, for example. The information of D11 from the P thus obtained is transmitted from the RAM to external circuitry bit-serially in the order of Y0(P, H0, H1, D1), Y1(H2, D2, D3, D4), Y2(H3, D5, D6, D7) and Y3 (D8, D9, D10, D11).
