signal_to_noise_C5510_C6713
Used on cellular phones to filter out
background noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).
Includes a tutorial on how to use statistics (correlation coefficient) to calculate the signal to noise ratio.
Realtime implementation using Texas Instruments TMS320C5510 DSK and TMS320C6713 DSK. Code mostly in C, except where it would be too slow and assembly language is used.

fft_plot
routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use:
>> n = 100 number of data points
>> dt = 0.01 spacing between samples
>> t = 0:dt:(n-1)*dt time vector
>> y = sin(2*pi*10*t) 10 Hz sin wave
>> fft_plot(y,dt) plot of signal in time and frequency domain
