MATLAB program for computing Signal-to-Noise Ratio (SNR) and Signal-to-Noise-and-Distortion Ratio (SNDR) through FFT analysis of pipeline analog-to-digital converter output signals, featuring spectral analysis and performance evaluation algorithms

Detailed Documentation

This MATLAB program performs Fast Fourier Transform (FFT) analysis on pipeline analog-to-digital converter (ADC) output signals to calculate Signal-to-Noise Ratio (SNR) and Signal-to-Noise-and-Distortion Ratio (SNDR). The implementation involves applying FFT to the ADC output signal using MATLAB's fft() function, followed by spectral analysis to distinguish fundamental signal components from noise and distortion harmonics. Key algorithmic steps include windowing the time-domain signal to minimize spectral leakage, identifying the fundamental tone's power, and calculating noise power across all frequency bins excluding DC component and signal harmonics. The program enables comprehensive performance evaluation of pipeline ADCs through quantitative noise analysis, supporting signal processing optimization and distortion characterization for high-speed data conversion systems.
