HIGH-DENSITY EMI FILTER DESIGN FOR DC-FEDMOTOR DRIVES



INTRODUCTION

Electromagnetic interference (EMI) is one of the major design challenges in motor drive systems, especially in applications where stringent standards need to be followed. EMI noise is usually defined as common-mode (CM) and differential-mode (DM) noise. CM noise is defined as the noise flows between the power circuit and the ground, while DM noise is defined as the current following the sam ....etc

B = FIR1(N,Wn) designs an N'th order lowpass FIR digital filter
and returns the filter coefficients in length N+1 vector B.
The cut-off frequency Wn must be between 0 < Wn < 1.0, with 1.0
corresponding to half the sample rate. The filter B is real and
has linear phase, i.e., even symmetric coefficients obeying B(k) =
B(N+2-k), k = 1,2,...,N+1.
If Wn is a two-element vector, Wn = , FIR1 returns an
order N bandpass filter with passband W1 < W < W2.
B = FIR1(N,Wn,'high') designs a highpa ....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

hey! can u plzz provide me d vhdl code for IIR digital low pass filter for equation Y(n)=X(n)+2(Y(n-1)) where Y(n) is present state and Y(n-1) is previous state o/p.
I hope u will provide me d code as soon as possible.
thank u.. ....etc

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

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 :
