Name: Spectrum Analyzer: Processor Exercise Using C Language with C Introduction (55x)
ID: m13809
Language: English (en)
Summary: This is a processor exercise in which students implement a spectrum analyzer using mixed C and assembly code. Students are to acquire a block of 1024 samples, apply a Hamming window, compute a length-1024 Discrete Fourier Transform using provided Fast Fourier Transform code, and display the magnitude-squared spectrum on an oscilloscope. Students will also compile and explore a reference implementation of an autocorrelation-based power spectral density (PSD) estimator. This implementation estimates the PSD of an IIR-filtered pseudo-noise generator.
Subject: Science and Technology
