We found this circuit in an Electronic Design. The main integrated circuit is the 4017. The frequencies are determined by the RC circuits as well as the duration of the generated pulse train.
With this circuit it is possible to use a control voltage to select audio signals that pass...
This CMOS oscillator includes the frequency divider to generate a 400 Hz signal and a 1.6 MHz...
The circuit presented uses an integrated circuit Sanyo, not very common in our day. This amplifier provides...
