Synchronous and Asynchronous Sequential Circuits- Basics and Design

A001_4497-L

Digital VLSI circuits are usually classifed into: 1) Synchronous Sequential Circuits 2) Asynchronous Sequential Circuits Synchronous Sequential Circuits If the transitions in a sequential circuit from one state to next state are controlled by a CLOCK, then the circuit is called synchronous … [Read more...]

Relay-The magnetic Switch:Basics and Working Principle

relay1

A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and most have double throw (changeover) switch contacts as … [Read more...]

Virtual Machines

Virtual machine is taken to be efficient, isolated duplicate of the real machine. This is explained using the idea of virtual machine monitor (VMM). This VMM has three characteristics - It provides an environment for programs which is identical with the original machine. Program runs this … [Read more...]

Phase Shifters and Phased Array Radars

interfer2

PHASE SHIFTERS Phase Shifters are devices, in which the phase of an electromagnetic wave of a given frequency can be shifted when propagating through a transmission line. In many fields of electronics, it is often necessary to change the phase of signals. RF and microwave Phase Shifters have … [Read more...]
