Operational amplifier
or op-amp, is a very
high gain differential
amplifier with a high
input impedance
(typically a few
MegaOhms) and low

Fourier Analysis
Fourier Analysis is the study of how a function

of trigonometric functions (sine and cosine).
It is the process of decomposing a function into

What is the effect of sampling on x(t)?
The sampling process generates high

Introduction
All electronic circuits need DC power
supply either from battery or power pack
units.
Many electronic equipment contain circuits
which convert the AC supply voltage into

DEFINITION
Signal is something that carries
information. It is a pattern of
variation of a physical quantity that
can be manipulated, stored, or
transmitted by physical processes.

Some of the important properties of solid materials depend on geometrical atomic
arrangements, and also the interactions that exist among constituent atoms or
molecules (Callister, 2007). To fully understand any topic is to understand the
