摘要： A scrambling system for an audio frequency signal in which an audio signal is divided into blocks, each block being formed of a plurality of frames, the plurality of frames are rearranged on a timebase in a predetermined order at every block so as to be encoded and the encoded signal is re-arranged on the timebase in an original order so as to be decoded, in which there are provided a first signal processing circuit for inserting a redundant portion into a portion between adjoining frames and timebase-compressing the frames in response to the redundant portions upon encoding, a control signal generating circuit for inserting a control signal other than an audio information into the redundant portions, a control signal detecting circuit for detecting the control signal upon decoding and a second signal processing circuit for removing the redundant portions in synchronism with the detected control signal and timebase-expanding the frames in response to the redundant portions. Therefore, even when the audio signal is transmitted through a system in a transmission path having a timebase fluctuation such as a transmission path of a VTR (video tape recorder) and the like the frequency band region of which is restricted, the signal waveform is not distorted and a noise is not mixed therein so that the scrambling communication having high quality and high reliability can be presented.

摘要： In tuning apparatus, a sensor senses when a tune indicating signal has been produced by the IF section so as to enable an adjusting circuit to change the tuning condition of the apparatus by a predetermined frequency step and then to disable the adjusting circuit if the tune indicating signal still is sensed following this frequency change so as to maintain the last-attained tuning condition. Alternatively, if the tune indicating signal no longer is sensed after the tuning condition has been changed by the predetermined frequency step, the tuning section is returned to its preceding tuning condition by this predetermined frequency step. Consequently, if the received signal is a high level signal at a frequency within a predetermined range from a broadcast frequency, the tune indicating signal is produced when the tuning condition of the tuning section differs from the broadcast frequency by this predetermined frequency step; and the tuning condition then is changed by this step so as to arrive at the desired broadcast frequency. If, however, the received signal is a low level signal, the tune indicating signal is produced only when the tuning condition of the tuning section coincides with a desired broadcast frequency, and then this tuning condition is changed by one step followed by a return of one step to the proper condition.
摘要翻译：在调谐装置中，传感器感测IF部分何时产生乐曲指示信号，以使得调整电路能够以预定频率步长改变装置的调谐状态，然后如果调谐指示在该频率变化之后仍然感测到信号，以便保持最后达到的调谐条件。或者，如果在调谐条件已经改变了预定频率步长之后不再感测到调谐指示信号，则调谐部分通过该预定频率步长返回到其先前的调谐条件。因此，如果接收到的信号是从广播频率的预定范围内的频率的高电平信号，则当调谐部分的调谐条件与广播频率不同的预定频率步长时，产生乐曲指示信号; 然后通过该步骤改变调谐条件，以达到所需的广播频率。然而，如果接收到的信号是低电平信号，则仅当调谐部分的调谐条件与期望的广播频率一致时才产生调谐指示信号，然后将该调谐条件改变一个步骤，然后返回一步到适当的条件。

摘要： In a teaching system having a central or master station and one or more student stations remote from the master station, there are provided, at the master station, at least one source of main signals in a first frequency band, which source may be constituted by a tape or other record player for reproducing teaching or instructional materials, a microphone or other source of audio signals from a proctor or supervisor of the teaching system, and a source of control signals which may include address signals for identifying one of the student stations and command signals for controlling various operations of the addressed student station. The audio and control signals are employed to modulate respective carriers so as to provide first and second auxiliary signals, respectively, in frequency bands which are removed from each other and from the first frequency band of the main signals, whereupon the main signals and the first and second auxiliary signals are multiplexed to provide a composite signal which, in turn, modulates a carrier of predetermined frequency suitable for being transmitted to each of the student stations.

摘要： A synthesis signal which was reproduced from reproducing apparatus and converted into an analog signal includes an analog information signal and a copy control code. The copy control code is modulated by a spread spectrum. A code reading unit of the recording apparatus extracts the copy control code by an inverse spread spectrum. A code changing unit changes the copy control code by a spread spectrum as necessary. An output signal of the code changing unit is converted into a digital signal. The digital signal is subjected to processes necessary for recording and is recorded to a recording medium.

摘要： Apparatus for transmitting and receiving signals for use with a so-called cordless telephone, in which an audio signal and an identification code signal are transmitted and received by both the handset and base unit of the telephone and when the identification code signal is not correctly detected, as might be caused by cross-talk interference, the transmitter is disabled and a vacant communication channel is searched for and a communication channel is changed to thereby prevent a cross-talk interference. The unit that does not correctly receive the code signal immediately disables its transmitter and searches for a vacant channel and, because the code signal had been alternately transmitted and received between the two units, the other unit detects the stoppage of code signal transmission, disables its own transmitter, and then also moves to the next vacant channel to await further transmission of the code signal.
