It’s helpful here to understand that there are two things involved with digital sampling: Of foremost importance is the sampling; secondarily, subsequent digitization allows us a number of conveniences. That is, sampling theory does not require digitizing—you can store the analog levels obtained by sampling a signal whose spectrum is below half the sample ...

Sampling is the process of making the x-axis (time) discrete and quantization is the process of making the y-axis (magnitude) discrete. You can sample without quantization (such as done with an analog sample and hold circuit). Quantization is introduced through rounding or truncation when the sampled analog signal is mapped to a digital representation. ...

Quantization and sampling are different things and they are treated mathematically very differently. However they usually happen both at the same time. Anything represented "digitally" (i.e. as a series of numbers in a computer or a digital storage device needs to be both sampled and digitized. This is typically done with a process called Analog-to-Digital ...

This is a great question and comes down to the AGC design and optimizing the available dynamic range on the ADC, given a receiver minimum SNR, sensitivity and interference rejection requirements. I first need to know or establish these requirements and then usually start a receiver design from the ADC options available within the cost, power and technology ...
