How to convert Analog signal into digital?
Ans. Analog Signal(input) → Sample & Hold circuit → Quantization → Encoding → Digital Signal (output)
Sampler takes samples i.e. records value of the analog signal at a specified time and this random values of sampled signal is quantized to defined levels and these levels are encoded by defined number of bits and thus digital signal is obtained.
