All the Digital Signal Processing Questions & Answers given below includes solution and link wherever possible to the relevant topic.Signal conveys information using gesture, action, and sound. The signal can be classified into two types one is analog and another one is a digital signal. Most of the signals are analog in nature means the signal is continuous with respect to time, to convert an analog signal to a digital signal we can use sampling and quantization. Analog signal first converts into the discrete signal using sampling and quantization n which the signal is sampled at a discrete interval of time. Once the discrete signal is obtained then the signal is converted into a digital signal. Signal processing is performed to analyze, modify, and synthesize the signal.There are three types of signal processing they are analog signal processing, digital signal processing, and mixed-signal processing. Digital signal processing is flexible in operation, low cost, and is a stable system. There are two types of signals are there they are analog and digital.
