What is the main purpose of oversampling in ADC (Analog to Digital Conversion)?

A) To increase the cost of the system

B) To reduce the effects of quantization error

C) To simplify the circuit design

D) To allow for better frequency response

Answer: D) To allow for better frequency response

Explanation: Oversampling in ADC helps to improve the frequency response and reduces the effects of noise and quantization error. It also simplifies the design of anti-aliasing filters.
