The Nature of Circles
What do you mean? When calculating the mean of a list of numbers, the obvious approach is to sum them and divide by how many there are. Suppose I give you a list of two numbers: 0 359 What i...

Simultaneously Computing a Forward FFT and an Inverse FFT Using a Single FFT
Most of us are familiar with the processes of using a single N-point complex FFT to: (1) perform a 2N-point FFT on real data, and (2) perform two independent N-point FFTs on real data [1–5]. I...

Multiplierless Exponential Averaging
This blog discusses an interesting approach to exponential averaging. To begin my story, a traditional exponential averager (also called a "leaky integrator"), shown in Figure 1(a), is commonly used... posted by Rick Lyons on Dec 5 2008 under Tips and Tricks

Free DSP Books on the Internet - Part Deux
Since Stephane Boucher posted my "Free DSP Books on the Internet" blog here in February 2008, I have learned of additional books on the Internet that are related to signal processing. I list those ... posted by Rick Lyons on Dec 4 2008

Computing the Group Delay of a Filter
I just learned a new method (new to me at least) for computing the group delay of digital filters. In the event this process turns out to be interesting to my readers, this blog describes the method... posted by Rick Lyons on Nov 19 2008 under Tips and Tricks

Computing Large DFTs Using Small FFTs
It is possible to compute N-point discrete Fourier transforms (DFTs) using radix-2 fast Fourier transforms (FFTs) whose sizes are less than N. For example, let's say the largest size FFT software ro... posted by Rick Lyons on Jun 23 2008 under Tips and Tricks

Frequency Dependence in Free Space Propagation
IntroductionIt seems to be fairly common knowledge, even among practicing professionals, that the efficiency of propagation of wireless signals is frequency dependent. Generally it is believed that lo...
