Understanding the Z-Transform III: Analyzing an FIR Filter
Let’s continue on with our tour of the Z-Transform for understanding digital system design. In this article we are going to look at an FIR Filter as an example system. We will examine the system using the Z-Transform and graph out the entire analysis. If you...
Signal Analysis II: Linear vs Logarithmic Sine Sweep
In one of my Github repositories I included 3 signals: Dirac DeltaLinear Sine SweepLogarithmic Sine Sweep I explained the Dirac Delta and why we use it in my article: What Is An Impulse Response? However, I have not explained why I bothered including...
Signal Analysis I: What is a Wave? An Introduction to Fourier’s Theorem
In audio programming, we are concerned with using computers to capture, measure, analyze and manipulate audio signals. If you are working with audio or DSP you will have to understand some basics of wave interaction. What is a Wave? For our most basic case, we can...
A Basic Understanding of Digital Audio
We get a lot of questions about DSP every day. In this article I am going to illustrate how Digital Audio works, and how your computer works with audio data. This is a high level overview that will introduce you to fundamental aspects of digital audio. A Familiar...
