Q1:

Two rectangular waveforms of duration t1 and t2 seconds are convolved. What is the shape of the resulting waveform?

A Triangular

B Rectangular

C Trapezoidal

D Semi-circular

ANS:C - Trapezoidal

The Shape of the convolved signal depends on the duration t1 and t2.
If both the rect signals have same duration then yhe convolved signal will be triangular in shape.
If t1 is not equal to t2 then it will be trapezoidal in shape.
