In this paper, the authors simulated the time-domain unit sample response of sine function and frequency-domain response of sine function. Digital filter plays an important role in today's world of communication and computation. Without digital filter, the authors cannot think about proper communication because noise occurs in channel. For removing noise or cancellation of noise they use various type of digital filter. In signal processing, there are mainly two types of filters exist. They are the Finite Impulse Response (FIR) filter and Infinite Impulse Response (IIR) filter.
