MAnalyzer is an FFT based audio frequency analyzer. Content can be displayed as either 1/3 octave bars or as a variable resolution FFT curve. MAnalyzer allows lots of functions including comparisons, magnitude normalization, averaging and smoothing. FEATURES: · Spectrum meter (64-bars),...

DFT plays important role in DSP and used in wide variety of applications like correlation and spectral analysis. Understanding quantization errors in its computation is an important aspect of its design either for s/w or h/w implementation.A complex DFT of N points has N complex (4N real)...

This package consist of a number of auxiliary functions that are helpful for analysing 1D and 2D signals such as surface profiles and surfaces and images. They are all built upon the built-in MATLAB FFT routine for fast execution and they replicate (when it is existing) the result produced by...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....
