In the Figure 1-19 (a), the VTl and VT2 form the Schmidt circuit to shape the input waveform; Rl and C1 form the integration circuit; VT3 is the buffer circuit; the VT4 and VT5 form the amplifier circuit. The main features of the circuit is that it has high noise immunity, adjustable signal level and circuit constants, and it is the basic frequency / voltage conversion circuit. In the Figure 1-19 (b), the output mostly uses operational amplifier, and the output part uses the frequency / voltage conversion circuit composed of transistors.
