AI Thread Summary
To design a bandpass filter with specific specifications using MATLAB, the process involves calculating the impulse response h(n) via the Fourier transform method for a linear phase FIR filter with 23 taps, a sampling frequency of 10 kHz, and a passband between 2.2 kHz and 3 kHz. The Blackman window is applied to the generated FIR filter coefficients to create the windowed impulse sequence hx(n). Delaying the windowed impulse sequence by M samples is necessary to achieve causal filter coefficients. MATLAB offers functions for direct FIR design, including the Remez Exchange Algorithm and various windowing methods. Utilizing these techniques will facilitate the design of the desired bandpass filter effectively.

Does anyone know the steps to design/ calculations of bandpass filter, linear phase FIR with these specifications?
a). N= 23 (number of taps) Freq sample = 10kHZ, Freq low= 2.2kHz, Freq high = 3kHz

b). apply a 23 tap to blackman windowing?

Any additional such as the comparison of the two FI design would be helpful, thanks

What learning resources do you have available for this question? What textbook are you using for filter design? What have you done so far on these questions?
 
I am first computing the impulse sequence h(n) via the Fourier transform method for bandpass filter. Then I multiply the fenerated FIR filter coefficients h(n) by the selected windows sequence of blackman windowing to obtain the hx(n), window impulse sequence. I delay the window impulse sequence hw(n) by M sample (N = 2M + 1) to get the causal windowed FIR filter coefficient ...

Is this correct?
 
use MATLAB, you can find functions for direct FIR designing using Remez Exchange Algorithm or using different Windows.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
