Interpolation Process Implementation:
Theory:
“Upsampling” is defined as the process of inserting zero-valued samples between original samples to increase the sampling rate. (This is called “zero-stuffing”.)...
Decimation process implementation:
Theory:
“Decimation” is that the process of reducing the rate.
“Down sampling” may be a more specific term that refers to only the method...
Steps involved in performing FIR filter operation
Step I: Let’s enter the pass band frequency (fp) and stop band frequency (fq).
Step II: And then get...
Where has IIR filters are digital filters with infinite impulse response. Unlike FIR filters, they have the feedback (a recursive a part of a filter) and are mentioned as recursive...
POWER SPECTRUM DETERMINATION OF GIVEN SIGNAL
THEORY: The power spectrum describes the distribution of signal power over a frequency spectrum. The most frequently used way...
Theory:
FFT is a most efficient algorithm used in speech processing, frequency estimation and communication. FFT utilizes full advantage of two symmetry properties in order...
Theory for autocorrelation:
Auto Correlation Function Autocorrelation function is a measure of similarity between a signal & its time-delayed version. It is represented with R(k)....
linear Convolution Theory:
Convolution is a mathematical way of combining the two signals to form a third signal. It is the only most vital technique in Digital Signal...
Theory:
Frequency analysis of discrete time signals is usually performed on digital signal processor, which may be general purpose digital computer or specially designed digital...
