In the world of digital signal processing, DSP, there are two basic types of signals which are often compared and contrasted with one another: continuous signals and discrete signals. While both...
After four years of studying DSP (Digital Signal Processing) as part of my Electronic Engineering Degree, I finally grasped this fascinating, if not elusive, subject. I did not fully appreciate...
If you're considering a career in digital signal processing, you might wonder how hard the field is. After all, it deals with the mathematical manipulation of digital signals. Although digital...
What Is The Fourier Transform? (Why we need it in simple terms)
If you are an electronic engineer, DSP or acoustics graduate, you may have come across the term "Fourier Transform" in your studies. Typically, the term is followed by pages of maths, which makes...
Time Series, Signals & The Fourier Transform (A basic overview)
What Is A Time Series? A time series is a sequence of data points measured at successive points in time. Time series data are often plotted as a line on a graph, with time on the x-axis and the...
