<p>PURPOSE:To make it possible to extract a signal from its beginning at any time by leading out all outputs of signal sources circulating endlessly in parallel and then by extracting one of circuits at a random point in time. CONSTITUTION:Sound source part 1, constiting of an adequate and plural number of sound sources, it formed by providing relatively-wide magnetic tape TA with adequate number (m) of recording tracks. For example, when a call signal arrives at circuit L1, command signal generating part 7 outputs a command signal so as to actuate detection part 2 via control part 4. Detection part 2 discriminates a signal channel, outputting a discriminating signal, from output signals input from sound source part 1 to output data of corresponding binary codes. By decoding the binary codes which are input, control part 4 controls the signal-line selective connection of matrix circuit 3 so that the signal line of the signal channel outputting the discrimination signal will be coupled with output terminal 31. A signal can therefore be extracted from its beginning at a random point in time all the time.</p> |
