Analog-to-Digital Signal Conversion

The process of analog-to-digital signal conversion consists of converting a continuous time and amplitude signal into discrete time and amplitude values. Sampling and quantization constitute the steps needed to achieve analog-to-digital signal conversion. To minimize any loss of information that may occur as a result of this conversion, it is important to understand the underlying principles behind sampling and quantization.

2.1 Sampling

Sampling is the process of generating discrete time samples from an analog signal. First, it is helpful to see the relationship between analog and digital frequencies. Let us consider an analog sinusoidal signal xx (t) = A cos (ωt + ϕ). Sampling this signal at ...
