Question

Given that the feedback factor is 0.6, find the time period of the circuit below.

(a) 0.331 seconds

(b) 0.303 seconds

(c) 0.276 seconds

(d) 0.606 seconds

I had been asked this question by my college professor while I was bunking the class.

My question is taken from Different Types of Multivibrators in division Multivibrators of Analog Circuits

Answer 1

Correct option is (b) 0.303 seconds

Explanation: T = (RXC + RYC)ln(1+β/1-β)

T = 22x10x10^-3xln(1.6/0.4) = 22x10x10^-3x1.38 = 0.303 seconds.
