WIDE RANGE BAND PASS FILTER
DESCRIPTION:
Third-Order Wideband Bandpass Filter
This circuit demonstrates the operation and characteristics of a wideband bandpass filter, constructed by cascading a second-order low-pass and a high-pass filter. As a result, a 300 Hz to 3 kHz bandpass voice filter is formed.
Experiments:
Set the function generator to 1 kHz and the oscilloscope's time base to 0.2 ms/DIV. Increase the input frequency, about 1 kHz at a time up to 4 kHz, constantl ....etc

Abstract

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc

Abstract
Three-party authenticated key exchange protocol(3PAKE) is an important cryptographic technique for securecommunication which allows two parties to agree a new securesession key with the help of a trusted server. In this paper, weproposed a new three-party authenticated key exchange protocolwhich aims to achieve more efficiency with the same security levelof other existing 3PAKE protocols. Security analysis and formalverification using AVISPA tools show that the proposed protocolis secure against various known attacks. Comparin ....etc

ComPass(Commuter Pass) Create a billing system using RFID tags that can be attached to a keychain to pay for public transportation( bus, ferry, subway). Frequent commuters will save time while not having to buy tokens or MetroCards. It could even be an extension of the EZ-pass program which would make paying for public transportation more convenient. ....etc

WHO WANTS TO PASS THE SOL’S



Africa


Beginning of Time



Earliest human findings date back 40,000 years.
Scientists believe humans first appeared over 2 million years ago.
The first humans were wandering hunters and gatherers.
They made simple tools and weapons from bones, wood, and stone.

I am Manzil Duarah a B.E final year student. My seminar topic for my final semester is A very linear low pass filter with automatic frequency tuning. I don't have the necessary documents for making the seminar report. So i wanted the full text document on this topic. So i would be very thankful if you help me out.
The abstract of the topic is as follows :
