Name: Spectrum Analyzer: Processor Exercise Using C Language with C Introduction
ID: m11827
Language: English (en)
Summary: This module describes 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.
Subject: Science and Technology
