181: Critical frequency
Critical frequency is the maximum frequency of the radio wave which is returned from a layer for normal incident.
182: Basics of Streaming Video
So you finally managed to get your website up and running, and now you want a video added to the site. Only thing is you don’t have the slightest idea why you can’t just copy paste a video into your site, don’t worry help is at hand. Videos are almost indispensable to your site if you are an educational site or if you are planning to make a multimedia rich site. However the important thing to understand is that simply embedding video is not an option. In fact the reason why sites use streaming videos is because streaming is much faster than embedding.
183: How to Throw an 80s Theme Party
So how fun would it be to go all out and throw an 80's theme party? Do you remember the days of the Rubik's Cube, Pac-Man, big hair bands, phrases like "totally awesome", and of course you can't forget Ferris Bueller? If you remember any of these you're on the right track, but it takes a few key ingredients to throw a sensational 80's party!
184: Cross Talk: Not Just an Angry Conversation
When two signals of slightly different frequencies are applied to a circuit, then because of third order action, the amplitude of the output voltage of one signal depends upon the amplitude of the other signal. Accordingly if one signal is amplitude modulated then because of cross modulation, amplitude of the other signal at the output of the circuit varies with the variation of the amplitude of the first that is the modulation gets transferred.
185: Frequency Mixer and Frequency Converter: How to Distinguish the Two
nIn a frequency mixer the radio frequency signal voltage if frequency and local oscillator voltage of frequency are applied to its input. The frequency mixer uses a device which presents non linear dynamic characteristics. Hence the two input voltages beat together or heterodyne with the mixer to produce output current having the components of frequency.
186: What the heck is a Multi Unit Steer-able Antenna System
Multi unit Steer-able Antenna System is an excellent diversity reception system and utilizes the some of the facts like short wave signals from a distant transmitter reach a receiver at certain preferred vertical angles depending upon the carrier frequency , distance involved, height of reflected ionized layer, ionic density of the reflecting layer.
187: How Power Sources Work
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 based or mobile that is ship board, automobile mounted, air borne or carried by men.
188: The Stages of Super Heterodyne Receivers.
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.

190: The Many Different Types of Antenna For Your System
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 reception it normally has omni directional characteristics on long, medium and short wave ranges.
