The implementation of a tuner in MATLAB environment

In music it is essential, that the instruments are properly tuned, they have to sound very clean alone or together with other instruments. For the tuning procedure we need an accurate, real-time and easy-to-handle tuner. Before the implementation I have examined the attributes of guitars...

Finite Impulse Response program in signal processing

This is a matlab program  in dsp using windowing techniques- fir windows. Here the various windowing techniques have been analysed and the graphs are plotted. The user can switch over from Hamming, Hanning, Blackmann windows to obtain the corresponding outputs. They can give the options to sele...

Signal Smoothing

Let s[n] be the signal corrupted by a random noise d[n] resulting in the noisy signal x[n] = s[n]+ d[n] . The objective is to operate on x[n] to generate a signal y[n] which is a reasonable approximation to s[n]. A simple approach is to generate an output sample by averaging a number of inpu...
