What is an audio spectrum analyzer?
A spectrum analyzer is a measurement tool that displays real-time frequency analysis of incoming audio signals. Spectrum analyzers display the results in a graph. ... The vertical axis shows the amplitude of those frequencies measured in decibels. A variety of spectrum analyzers offer different and useful features.
How does an audio spectrum analyzer work?
Swept spectrum analyzers work by using one or more notch filters (or mixers) to measure the signal amplitude at a given frequency, and by changing (or sweeping) the frequency of this filter a plot of amplitude against frequency can be constructed.
What does a spectrum analyzer show?
A spectrum / signal analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.
