Q1:

Which of the following periodic waveforms will have only odd harmonics of sinusoidal waveform?




Select the correct option using the codes given below Codes:

A 1 and 2

B 1 and 3

C 1 and 4

D 2 and 4

ANS:A - 1 and 2

The conditions for a signal s(t) to have odd harmonics of sinusoidal waveforms alone are given by (i) , where T is the period and (ii) s(t) = - s(t) [i.e., odd function] The waveforms (1) and (2) satisfy condition (b).
