Question

A 12 kHz pulse wave-form is amplified by a circuit having an Upper cut-off frequency of 1 MHz. The minimum input pulse width that can be accurately reproduced is-A-83.33 &mu; secB-1 &mu; secC-0.1 m secD-3.5 m sec-B-1 &mu; sec

APTITUDE CRACK · Accepted Answer

The correct option is  B 1 &mu; sec  tr = 10% Pω = minimum Power(P) = 10 tr 10 x 0.35 μ sec = 3.5 μ sec. Note: The I/P Pulse will be severely distorted if the rise time is more than 10% of Pulse width.
