For the given circuit, find the time period of the output waveform, given that the diode is used is of Silicon and the supply voltage being applied is ±15V. The feedback factor is 0.4. Correct Answer 11.12 ms

T = RCln(1+Vγ/VSat/1-β) T = 10x2x10-3xln((1+0.7/15)/0.6) = 20×10-3ln(1.0467/0.6)=20×0.556×10-3 T = 11.12 ms.
