摘要： A carrier current telephone system is provided for buildings. Transceivers are located where desired. The transmitter portion includes means for establishing a carrier signal and applying the same to the AC circuits in the building. Further means are provided for generating a subcarrier signal which is encoded on the carrier signal by frequency modulation of the carrier. Further means are provided for encoding the audio or data signal upon the subcarrier signal by frequency modulation of the subcarrier. Exclusive-OR gates are used in a voltage controlled oscillator for the subcarrier signal generator. Unique phase lock loop FM demodulators are used. Each comprises one CMOS 4070B exclusive-OR gate package, five resistors, one potentiometer, and three capacitors, with one of the exclusive-OR gates performing the phase detector function.

摘要： A multiple signal carrier transmission apparatus and method for broadcasting stereo sounds to an audio output device uses three related carrier frequencies on which are modulated the sum of first and second stereo channel signals and the first and second stereo channel signals themselves. The composite multiple carrier frequency signal is transmitted to a receiver which separates the three carrier frequency signals to generate a separate left channel signal, a right channel signal and a composite center channel, monophonic, signal which is the sum of the first and second channel signals. A detector monitors the signal strength of each separate left and right channel signal to detect a decrease in either channel output below a threshold. When a decrease below the threshold is detected, the center sum signal replaces the left and/or right channel signal having the diminished signal strength for output through the appropriate speaker to minimize channel fade out.

摘要： A high frequency signal transmission apparatus includes a transmitter for transmitting received signals from a signal source as a modulated signal on a high frequency 900 MHz carrier to a remote receiver. The remote receiver converts the high frequency carrier in at least one conversion step to a lower frequency carrier signal. The lower frequency carrier signal carrying the modulated signal is then converted to an audio output or to another carrier signal and retransmitted as a modulated second signal to another remote receiver capable of demodulating the signal and broadcasting the audio sounds or video images. The oscillators in the transmitter and receiver are selectable to operate at discrete frequencies. Automatic fine tuning control is provided in the receiver to accommodate drift of the oscillator in the receiver.

摘要： A cordless remote telephone unit communicates with a telephone line through a stationary self-powered base unit. The base unit is not plugged into an electrical household receptacle and is therefore completely portable to any location having a telephone jack. The remote unit is portable to any location within the radio range of the base unit. The base unit does not require a household electrical receptacle because non-rechargeable batteries are used in the base and remote units, so there is no need for a battery charger. Moreover, power consumption is minimized when the system is idle by cycling the battery power in both the remote and base units. As communication begins, continuous battery power is provided in place of the cycled power in the base unit in response to receiving from the remote unit a 5 KHz activation tone, a security code and a 22 Hz pilot tone, or in response to a ring received from the telephone line. After communication is established between the two units, the base unit derives reliable power through its hook switch directly from the telephone line using a power regulator suited for the purpose, further reducing power demand on the batteries. Power cycling in the remote unit is replaced by continuous battery power in response to receiving from the base unit a ring tone generated by the base unit ring detector, followed by a security code, or whenever the remote unit hand set is picked up by the user. In one embodiment of the invention, the remote unit handset is connected to a remote unit chassis by a cord, and the remote unit radio receiver and radio transmitter circuits use the cord as their antenna.

摘要： A cordless telephone system includes a control unit having a speaker, a microphone and control circuitry for selective operation in a "normal" mode for communications between the handset and an outside party, a "local answer" mode for communications between a party at the control unit and an outside party, an "intercom" mode for communications between parties at the control unit and the handset and a "3-way" mode for communications between parties at the control unit and handset and an outside party. A microprocessor so responds to ring detect, control and switch-generated interrupt signals as to obtain the desired communications.
