TSP #9 – Tutorial on Passive Filters, Data Transmission and Equalization

In this episode Shahriar explores the world of filters! Starting from a simple lumped RC filter, he briefly covers the theory before moving onto measurement techniques. The bandwidth of the filter is verified experimentally in the time domain. A more complex RLC band-stop filter is also demonstrated with a tune-able Continue reading TSP #9 – Tutorial on Passive Filters, Data Transmission and Equalization

TSP #8 – Tutorial on Linear and Non-linear Circuits

In this episode Shahriar investigates the impact of linearity and distortion on analog circuits. The source of a non-linear input/output characteristic is presented in three different domains: mathematical, time domain and frequency domain. After the theoretical discussion, a sample circuit is built and tested to illustrate real time signal distortion. Continue reading TSP #8 – Tutorial on Linear and Non-linear Circuits
