Synchronous clock signal is input to a cascade of timer circuit composed of two LM122H, then the synchronization clock is converted to the desired width of the pulse (Fig. 10μs) which will be add to LF198 LOGIC end (8 feet) as the sampling and holding control signal . The signal is input LF198's pin 3. The input signal contains a large number of noise component with magnitude higher than the useful signal, after the detector, the output signal's noise is filtered off, a pure signal will be output. The value of R3 should make 6-pin voltage be 0 ~~ 3V.
