*15.43 Consider a bistable circuit having a noninverting transfer characteristic with L+ = −L− = 5 V, VTL = −1 V, and VTH = +1 V.
(a) For a 0.5-V-amplitude sine-wave input having zero average, what is the output?
(b) Describe the output if a sinusoid of frequency f and amplitude of 1.1 V is applied at the input. By how much can the average of this sinusoidal input shift before the output becomes a constant value?
(a) either +5 V or −5 V; (b) symmetric square wave of frequency f, lagging the sine wave by 65.4°, having ±5 V swing; 0.1 V
