A Schmitt Trigger circuit shown in figure 2 is employed in a switching circuit in which Vsat = 10 V, Voc = 2 V, %3D the switching point is at 1 V and the width of the hysteresis band is 800 mv. a) Carry out a full analysis of the circuit and determine the values of the resistors R3 and R, if R4 = 100 kn, and R2 = 10 kn. [11] %3! b) Draw a full labeled voltage transfer characteristic of the ST circuit indicating details of the upper and lower threshold voltages, Vsat and the switching point.
