The Heterodyne Principle and the Superheterodyne Receiver

During World War I, Edwin Howard Armstrong invented the superheterodyne Rx as an alternative to the Tuned Radio Frequency (TRF)

When it comes to practical applications, digital filter design is one of the most important topics in digital signal processing.

One of the most attractive properties of a Finite Impulse Response (FIR) filter is that a linear phase response is

One question I am frequently asked is regarding the definition of Fourier Transform. A continuous-time Fourier Transform for time domain

One of the most common questions DSP beginners have is how to generate the signals (particularly, sinusoids) and view their
