                                                       Futuristic crystalline electricity PIEZO-ELETRIC EFFECT is a ability of crystals to generate a voltage in response to applied mechanical stress.This principle can be applied to obtain...

How to clean a vehicle fuel injector? A dirty fuel injector can cause blockages, which in turn can cause various problems in the engine. These problems include an increase in fuel consumption, poor performance and emissions so there are two...

Internet Routing devices are generally called as Gateways.Nowadays,the term gateway refers to a device which performs application-layer protocol translation between the devices. Interior Gateways: Interior gateways refer to the devices which...

UDP-User Datagram Protocol It is a connectionless transport layer protocol,which belongs to the Internet protocol family. Basically UDP acts as an interface between the IP(Internet Protocol) and Upper layer processes.UDP protocol ports...

The basic processes in digital transmission of analog information are sampling, quantizing and encoding. Sampling: The sampling theorem states that the signal may be reconstructed without any error from regularly spaced samples taken at the...

1. Frequency range used in lab? 2-4GHz which falls in S band.   2. General frequency range? C and KU band C band=6/4 GHz Ku band=14/11GHz   3. What type of antenna is used in lab? Helical type of antenna is used in lab.   4. C/N...

A two – tone test method, determines the presence of inter-modulation distortion. Two sinusoidal frequencies of equal amplitude are introduced are introduced into the system under test. The two frequencies are spaced close together with reference...

Inter-modulation Interference: The inter-modulation products generated within the satellite transponder as a result of the amplification of multiple carriers by the TWTA that exhibits both amplitude non-linearity and phase nonlinearity cause...

Delta modulation (DM) is a way of digitizing a voice waveform, transmitting the digits, and reconstructing the original analog waveform that avoids the quantizer and A/D and D/A converters employed in PCM . In linear delta modulation(LDM) the...

  The design of a satellite communication system is a complex process, involved compromises between many factors in order to obtain the maximum performance at an acceptable cost. Several factors dominate the design. These are · The weight of the...
