Circuit Analysis Modeling: ORCAD - SPICE Simulation and Tutorial (Voltage Divider)

As a schematic editor, OrCAD allows you to draw circuit schematics. The program has a nice collection of circuit parts or components to allow you to perform their assignments and laboratory exercises.

PSPICE is an electrical simulator that allows you to model the operation of circuits whose schematic was prepared using ORCAD. Students can now check for correct circuit operation before building the circuit in the lab.

The student version of ORCAD runs PSPICE without leaving… Continue

Basic Introduction to Active Filters and its Applications

Here is a short introduction to active filters and its applications. Active filters have comparable frequency selective performance when compared to passive filters. Active filters require power since operational amplifiers are involved to provide gain but do not require inductors since they can be large and lossy, especially for low frequency applications.

Briefly, let's begin the talk about the electric filter invented during World War I. These filters and… Continue

Overview and Introduction to the z-Transform (Polynomial & Rational Functions)

Here's the first of a series on the z-Transform. Comments are welcomed.

We introduce the z-transform bringing polynomials and rational functions to help analyze linear discrete-time systems. The discrete-time convolution (or FIR convolution) is equivalent to polynomial multiplication and algebraic operations in the z transform domain can be translated as combining or decomposing linear time-invariant (LTI) systems. The most common z-transforms are rational functions, that is, the… Continue

Circuit Analysis - Thevenin Equivalent and Resistance - Part 1

In many design instances, we frequently need to connect between circuits requiring an interface. As a result, there are analytical techniques used to handle these situations.

Usually, signals from another circuits feeds into a another part of a circuit, called a load circuit. The one generating the signal is called the source circuit. This interaction between the source and load circuit at the interface is a key design issue.

One of the most valuable analytical tools to… Continue
