Introduction to Electrical Components

Resistor: A Resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistance: opposition to flow of current. Type of Resistors: Carbon composition, Carbon pile, Carbon film, Printed carbon resistor, Thick and thin film, Metal film, Metal oxide film, Wirewound, Foil resistor Types of windings in wire resistors Common Bifilar Common on a thin former Ayrton-Perry Color Code:…

Amplitude Modulation

introduction: In amplitude modulation communication system ,speech or music is converted into electrical signal by using a device like microphone. The electrical signal is called message or baseband signal. The message signal is then used to electrically vary the amplitude of a pure sine-wave called the carrier. The carrier usually has frequency much greater than…

Introduction to Programming with MASM

introduction: Assembly language are a family of low level languages for programming computers. It implements a symbolic representation of the numeric machine codes and other constants needed to make a program. A utility program called an Assembler is used to translate assembly language statements into the target computer’s machine code. Using an assembler it is…

Introduction to INT Command

introduction: In other programming languages such as C/C++ int command is basically a data type “integer” and int can be input from user or defined value but in emu8086 int (interrupt) command is little bit different so in assembly language we used it to read a character from keyboard, to display a  character or string…

Signals and Signal Space

signals Any quantity that can be represented in terms of time axis or function of independent variable time is called signal. Signal may contain data or information. Weathers are also form of signal they continuously changes with time. systems They are used to process signals. They can modify them and can provide us a lot…
