The High frequency attenuation in shielded distribution cable has been extensively studied. But in the case of solid dielectric cable, this has not been done. A solid dielectric cable has a bit more complex structure including the semiconducting “bedding” layers and a moisture barrier.high frequency loss is created by these sources.The purpose of these bedding layers is to seal the cable against moisture ingress and also accomodate for the thermal expansion of the cable. The cables studied here are the ones with a corrugated copper sheat ....etc

A High Data Rate Frequency Hopping Modulation Scheme
Theme:ECE/Digital Communications

Submited By:

ABSTRACT
There is a need to select the 'first step up' modulation scheme for higher data rate frequency hopping systems. This is seen as one step in a longer journey where considerably higher data rates are used. In order to make this progression viable, the first step should be taken with a well proven modulation scheme. An ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

HIGH FREQUENCY AMPLIFIER
Objective
 To amplify the low frequency sound through the high sensitivity microphone.
 To provide a very clear voice of any soft and unpleasant sound using condenser microphone.
 R6-C4 network is used to RF-decouple positive-supply pin 6 and R8-C7 is an optional Zobel network that ensures high frequency stability when feeding an inductiveheadphone load.
 Capacitor C6 (22μF, 16V) wired between pin 7 ....etc

Study of interaction of pacemaker electrode with high frequency RF fields
The influence of radio-frequency fields on pacemaker operation has been studied by many. The need to know about influence of cellular phones on the device operation is the driving force behind these studies. This is serious concerning the safety of the patients. a wide band behavior of pacemaker lead is described in this article to identify and isolate the dangerous frequency bands in the spectrum. Medical and engineering sciences use completely different method ....etc
