Zero-crossing signal detection circuit
The core component of the circuit shown is the operational amplifier LM311 . The operational amplifier is used to form a voltage comparator. When an AC signal
is added to the input terminal, when a signal higher than zero level is input, the output is high level, and when a signal lower than zero level is input, the When the signal is input, the output is zero level .
