Spurious responses peculiar to super heterodyne receivers only are image frequency signals, signals if intermediate frequency, harmonics of intermediate frequency generated by the second detector and strong signals of twice the intermediate frequency. General spurious responses are cross talk and cr

In a radio transmitter power supplies are required to provide anode and grid screen voltages, grid bias voltage and filament voltages. The nature of basic supply used for any transmitter depends primarily upon its size, upon its output carrier power and also on whether the transmitter is ground base

Radio antennas have two fold functions. First of these functions is to radiate the radio frequency energy generated in the transmitter and fed to the antenna by a transmission line. In this capacity the antenna acts as the impedance matching device to match the impedance of the transmission line to

There are different stages of a super heterodyne receiver namely antenna or aerial, radio frequency amplifier, frequency converter stage, intermediate amplifier stage, second detector, audio frequency amplifier and loud speaker.

The word heterodyne means to mix. Heterodyne reception stands for the radio reception after covering the modulated carrier voltage into similarly modulated voltage at a different carrier frequency. Thus the heterodyning involves a simple change or translation of carrier frequency

The receiving aerial intercepts electromagnetic waves. The voltage induced in the receiving aerial is fed to the receiver input circuit through the antenna coupling circuit. An ideal receiving aerial must receive efficiently all the desired signals without wave band switching. For broadcast receptio

In this day and age when satellite radio is the big kid on the block, it is important to understand how it works. This article will supply you with the basic information about how digital signals work and therefore how satellite radio works.

This article will explain to you what AMplitude Radio Transmitters are and how they work.

Understanding how radio receivers work is important if you are an avid music fan. This article will explain to you how the Direction Coupler works and why it is so important in the receiver component of your system.

This is an article about Satellite Radio System, how they came about and what types are out there for you to choose from.

Here you will learn about the secrets of satellite radio and why you should consider making it a purchase in your near future.

The following article will help you learn everything that you need to about Surface Wave Propagation. When the transmitting and the receiving antennas are close to the surface of the earth, the space is negligibly small and the surface wave alone is of importance, thus the day time propagation of t

According to this method of classification transmitters can be classifies as Long wave, Medium wave, Short wave, Very high Frequency , Ultra high frequency and Micro wave transmitters. This article will give you information to help you understand the differences between them and how they work.

Methods of amplitude modulation can be put in the two categories namely Linear modulation methods and Square law modulation methods. Linear modulation method utilizes the linear region of the current voltage characteristics of the amplifying device that is transistor or electron tube. Square law mod
