摘要： A channel selection device for a multi-channel receiver includes a plurality of cascade connected shift register stages, each stage having two outputs, for sequentially shifting a binary coded signal from one stage to another under control of a shift pulse. Channel selection switches, each being coupled with a respective one of the two outputs of each of the shift register stages, are provided for bringing a selected shift register stage to a channel selecting position and a variable capacitance tuner is connected to respective ones of the outputs of each of the shift register stages through respective potentiometers. A simultaneous channel selection protection means is provided for causing only a single stage of the shift register stages to be brought to the channel selecting position when at least two of all of the channels of the devices are simultaneously selected by an erroneous operation.

摘要： A sound generating system comprising means for producing signals of fundamental frequency, and means for generating formant frequency signals of frequency higher than the fundamental frequency which starts oscillation synchronizingly with said signal of fundamental frequency and continues said oscillation only for a desired length of time during the period of said signals of fundamental frequency, wherein said signals of formant frequency are generated at the same starting point for each frequency interval as said signals of fundamental frequency. Sounds thus produced consist of a fundamental frequency component and harmonic components, and the frequency spectrum of said sounds presents a peak in a formant frequency, so that the system eliminates the necessity of using an electrical filter having complicated frequency characteristics in electrically producing sounds having a complicated frequency spectrum.
