入力信号e2，…eN-1についても同様である。 The input switch SW 10 sequentially switches 1 to N-1 input signals and supplies them to the preamplifier 2, and does not select the Nth input signal. If the first input signal e 1 is selected, this signal is supplied to the sample and hold circuit 3 via the preamplifier 2 . At this time, the selector SW 11 is selected to be held in the sample and hold device SH 1 , and the sample signal +V 1 is given to the sample and hold device SH 1 in response to the turning on of the switch SW 2 in synchronization with the marking operation. ,
Input signal e1 is sampled and held. On the other hand, the selection switch SW 3 is off because it is not receiving the on signal from the switch SW 12 , so the preamplifier 2
The output signal e1 is given to the servo unit 5,
The recording section 6 performs instructions and recordings corresponding to the magnitude of the input signal e1 . The same applies to the 2nd to N-1th input signals e 2 , . . . e N-1 .
