Frequency Divider

Frequency Divider

Circuit Description

This is a classic divider of frequency via two. It is achieved with a
classic circuit T-flipFlop, round IC1 [ 4011 ]. In the circuit, the
frequency of network, after are limit the negative half-s period of sine
wave and transform in square wave, are divided via two. Thus for
frequency50 HZ, we will take in the exit pulse of frequency 25 HZ. The
supply of circuit it is + 5V and does not need high benefit in current.
