Sketch the spectrum and determine the value of the Nyquist r

Sketch the spectrum and determine the value of the Nyquist rate of the signal.

Sketch the spectrum of the signal x(t) = sin^3(400 pi t), and determine value of the Nyquist rate for this signal.

Solution

The nyqiist rate of above signal os 2*3*f

f=200

Nyquist rate is 1200hz

Sinusoidal signal is given with power 3

While elobrating we got highest frequency as 3f

Exploration os done based on sin3f formula
