Linear-phase DC Removal Filter
This blog describes several DC removal networks that might be of interest to the dsprelated.com readers. Back in August 2007 there was a thread on the comp.dsp newsgroup concerning the process of r...

Correlation without pre-whitening is often misleading
White Lies Correlation, as one of the first tools DSP users add to their tool box, can automate locating a known signal within a second (usually larger) signal. The expected result of a correlation i...

Handling Spectral Inversion in Baseband Processing
The problem of "spectral inversion" comes up fairly frequently in the context of signal processing for communication systems. In short, "spectral inversion" is the reversal of the ...

Computing Chebyshev Window Sequences
Chebyshev windows (also called Dolph-Chebyshev, or Tchebyschev windows), have several useful properties. Those windows, unlike the fixed Hanning, Hamming, or Blackman window functions, have adjustab...

Spectral Flipping Around Signal Center Frequency
Most of us are familiar with the process of flipping the spectrum (spectral inversion) of a real signal by multiplying that signal's time samples by (-1)n. In that process the center of spectral rotat...

A Differentiator With a Difference
Some time ago I was studying various digital differentiating networks, i.e., networks that approximate the process of taking the derivative of a discrete time-domain sequence. By "studying" ...

A brief look at multipath radio channels
Summary: Discussion of multipath propagation and fading in radio links Radio channels, their effects on communications links and how to model them are a popular topic on comp.dsp. Unfortunately, for m...

Delay estimation by FFT
Summary: The delay between a signal and a reference appears in the frequency domain as linear phase shift. It can be estimated with subsample accuracy using FFT methods.This article provides a ...
