⇒ it satisfies the half wave symmetry, so that it contains only odd harmonics.

⇒ It satisfies the even symmetry. So b_{n} = 0

The steady state error of a unity feedback linear system for a unit step input is 0.1. The steady state error of the same system, for a pulse input r(t) having a magnitude of 10 and a duration of one second, as shown in the figure is

A periodic voltage waveform observed on an oscilloscope across a load is shown. A permanent magnet moving coil (PMMC) meter connected across the same load reads

where y is the output and u is the input. The system is controllable for
