A Digital Filter is described by the following. difference equation: Y(n)=0.5x(n) 0.5(n-2) - Find the transfer function ..

What is lead compensator? Draw its circuit diagram and derive the expression for the transfer function of lead compensator. Solve it fast fast plz

1. Fast help needed to answer this Physics question. Check image.   Postive feedback for right answer :)

How can I design an active filter circuit (just the low pass) using resistors, capacitors, and op-amps that will implement the transfer function. You will need to factor the function into cascade functions in order to make this easier. I jus want the drwan design with a litte explanation if possible.

Consider the following sampled signal x[n]. What is the cyclic frequency in the sampled signal if the signal was sampled with a sampling frequency of 40 Hz? x[n] = 1 + 2cos((pi/4)n +(pi/3))

Design an ACTIVE band-pass filter for the midrange part of a loudspeaker so that the bandpass region is 400 Hz-2000 Hz (as defined by the -3dB points). Design the circuit so that the absolute gain is 2. a. Draw the circuit diagram and specify the resistor and capacitor values. Assume you can use either 100, 330, 500, or 1000 Ohm resistors and can select any value of capacitor. b. Sketch the frequency response (Gain [dB] vs. frequency (Hz)). Note that you will need to convert your gain to dB before plotting. Magnitude (dB) 15 10 5 midrange 12 1 -5 -10 -15 -20 -25 10 100 1,000 Frequency (Hz) 10,000 100,000

Solve using the concpts of Digital Signal ProcessingShow each formula wherever necessary and please show all the steps of the design process

(b) High-frequency ECG biopotentials analysis in the ST-T segment of a high-resolution ECG signal recording requires the analysis of signal components above 30 Ilz and below 800 Hz. Design a first order band pass passive filter to accommodate this specified frequency bandwidth. Sketch the circuit configuration. You may use an op- amp buffer stage in your circuit design.

A bandlimited signal of max frequency 5 kHz is sampled. What will be the valuenof the Nyquist's sampling frequency?

3. What role does the RC time constant play in a filter circuit ?. In designing of a filter following a rectifier the RC time constant is desired to be long. Why this is so ?
