Q3. Write the equation for the time domain signal and how to convert this signal into frequency domain
Ans. 
The equation for a time domain signal can be converted into the frequency domain using Fourier transform.
• The equation for a time domain signal is typically represented as x(t) or f(t).

• To convert this signal into the frequency domain, we can use Fourier transform which decomposes the signal into its constituent frequencies.

• The Fourier transform equation is given by X(f) = ∫[x(t) * e^(-j2πft)] dt, where X(f) represents t...read more
