Summary -
Performs an error-free optimization of a stereo output from 20Hz to 20Khz.
The white noise is fed into the left and right stereo inputs. The amplified noise from the speakers is then picked up by an on-board electret condenser microphone, which provides the signal to the Spectral Analyzer.
The Spectral Analyzer, White Noise Generator, and display decoder/driver were all implemented from a single Cypress Microsystems CY8C26443 PSoC chip.
delabs Notes -
This is an interesting project to try out to learn how to use a PSoC, There are other good examples in the contest page at circuit cellar.
