Hello guys
Here I have this portion of the circuit which I cant really understand what it is doing and I want to solve it, so I can understand it. The inverting input is having a 2 signals and there peak is 5V, while on this inverting input we have this transistor with analog switch,this analog switch is being switched by a delay signal whose on time is 50us, this is the portion I am confused in. So I want tips/suggestions to how to understand this circuit and how to solve it, So I could understand why they used this transistor and switch part in this circuit. The value of capacitor is 100nf.
opamp rail voltages 10.6V and ground
