6. EXPLANATION OF OUTPUT PULSE SP, CP, TP

1) SP1 - SP10 (Single Pulse)

When a single key is depressed, after checking the 12-bit receiving data, if the data agree, a single pulse is output.

The output is raised from “L” level to “H” level and returned again to “L” level after about 107 msec.

2) CP1 - CP6 (Continuous Pulse)

Continuous pulse is output by the first latch pulse after key ON. Output is kept at “H” level as a long as a continuous

signal is input.

When the key is released and continuous signal is stopped about 160 msec later, output is reversed to “L” level by

the last latch pulse.

Further, CP1 - CP6 are able to output simultaneously in parallel method, maximum sextet outputs at “H” level by

continuous signals sent from the transmitter.

These outputs are optimum as outputs of REC-PLAY, REC-PAUSE and CUE/REVIEW of a tape deck.
