Questions and Answers

What is the main purpose of an anti-aliasing filter in the context of analog-to-digital conversion?

To digitize the analog signal and hold it for quantization and encoding

To optimize the sampling frequency and price ratio

To improve the resolution and reduce noise in the sampled signal
