This tutorial is going to cover the topic of negative resistance. At first, it might seem like a strange idea that you could have a current flowing in the opposite direction of an applied voltage; but, hopefully by the end of this tutorial you will have a better intuitive understanding of what a negative resistance… Continue reading

# How to Compute the IFFT using only the forward FFT

How can you calculate the IFFT (Inverse Fast Fourier Transform) using only the forward FFT (Fast Fourier Transform)? It is easier than you think! Read on to find out how. Cheat-Sheet: Just tell me how! Derivation of the Method Cheat-Sheet: Just tell me how! Let’s start with just saying straight out what you do. Take… Continue reading
