Scaling a Network's Gain: A Note For DSP Beginners

Rick Lyon's Blog on DSPRelated -

This blog briefly discusses a topic well-known to experienced DSP practitioners but may not be so well-known to DSP beginners. The topic is the proper way to scale a digital network in order to reduce the network's gain. Digital Network Scaling Figure 1 shows a collection of networks I've seen, in the literature of DSP, where scaling is...

Stereophonic Amplitude-Panning: A Derivation of the

Rick Lyon's Blog on DSPRelated -

In a recent Forum post here on dsprelated.com the audio signal processing subject of stereophonic amplitude-panning was discussed. And in that Forum thread the so-called "Tangent Law", the fundamental principle of stereophonic amplitude-panning, was discussed. However, none of the Forum thread participants had ever seen a derivation of the Tangent Law. This blog presents such a derivation and...

A Brief Introduction To Romberg Integration

Rick Lyon's Blog on DSPRelated -

This blog briefly describes a remarkable integration algorithm, called "Romberg integration." The algorithm is used in the field of numerical analysis but it's not so well-known in the world of DSP.

To show the power of Romberg integration, and to convince you to continue reading, consider the notion of estimating the area under the continuous x(t) = sin(t) curve based on the five...

Microprocessor Family Tree

Rick Lyon's Blog on DSPRelated -

Below is a little microprocessor history. Perhaps some of the ol' timers here will recognize a few of these integrated circuits. I have a special place in my heart for the Intel 8080 chip.
