filter specification a. What kind of filter is this? b. What is the transition band of the filter is given as ₂ = 0.4, , = 0.5, ₁ = 0.01, &₂ = 0.00001, c. Draw the absolute specification d. What is the specification in relative? e. Draw the relative specification. f. If the filter is applied on a signal sampled at 100 kHz, what are the frequency edges in Hz?

Design a first order active low pass filter using a single ideal Operational Amplifier (Op-Amp) as follows:  a) Draw the circuit diagram of the filter.  b) Derive the transfer function of the filter.

Design a high pass filter with a cut of frequency of K1 and a passband gain of K2. Take K1 equal to 27 in kHz and K2 is the 7 (b) Plot the Bode plot of the frequency response of the designed circuit using a python script and validate your answer. (c) How would you increase the passband gain by a factor of five without changing the cutoff frequency?

For the filter: a) Determine type of filter and the cut-off frequency (Fc). Determine the peak voltage at the cut-off frequency (Fc). b) Find GAIN (Vo/Vi) at f = .1*Fc . Find GAIN (Vo/Vi) at f = 10*Fc . c) Determine the frequency at which GAIN = .4 (i.e., Vo = .4*Vi) . Draw the “Frequency Response Plot” in “Log-Log” format .

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

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 ?

-3dB point in frequency response of an active filter corresponds to  A.   absolute value negative 3dB of gain   B.   decrement of 3dB from maximum gain   C.   minimum gain attained   D.   minus 3dB of average gain value

please answer question 1.b quickly… please answer base on my matric number not as same like question.. my matric no is 201061325 so the last 3 digit is 325 so the selected low cut-off frequency is equal to the 32 khz while the high cut-off frequency is 5khz … so use the value that i give... thank you
