Abstract
PURPOSE: To attain modulation keying for the low-frequency range and high-frequency range by switching modulation forth and back from the intermediate transition point of a shift register after shifting the output signal of a data reproducing circuit for a standard play tape as many times as a required number of bits.
CONSTITUTION: A reproduced signal from tape recorder DR is led to clock pulse generating circuit CG after passing through waveform shaping circuit WS to detect information on a keyboard, volume and pedals. A signal obtained from demodulator D via synchronous separating circuit SDC and the output of pulse generating circuit CG are received by address control counter AC. With signals from word pulse generating counter WPG and another address control counter AC, address latch circuits AL1WAL14 are selected. A demodulated signal from demodulator D is inputted to shift registers SR1 and SR2 and shifted there, so that modulation will be changed over by change-over switch DS.
