Hi.
I want to ask a question about BJT's version of a Schmitt's trigger.
How would you define this two threshold points VL and Vh.
Vh is when Vin rise towards Vcc and Q1 start to conduct Ic1 current and Ic1 pulls current away from the Q2 base. And eventually Q2 start to coming-out from the saturation region and positive feedback kicks-in.
So to be able to find this threshold point I write these equations
How to write the equation for this point?
