Obviously, as your diagram shows, you need to sample faster than 2f. Applying that sampled signal to a sinc **filter** will reconstruct the signal.

Is the above rule a sufficient condition for MIMO feedback stability?You can not understand contents I posted at all.
Modern control **theory** is surely useful for judging stability of MIMO System.
Your complex **filter** is formulated by using state space variable equations.
So modern control **theory** is straight for

Nowardays, except if the goal is to learn the concept step by step, we no longer have to deal with the **theory** behind how this is done to implement digital **filter**s in practice, but we just insert the performance parameters in one of the available online tools on the web and take the C code there, ready to use. The main thing you need to know is that

I started to design microstrip band-pass **filter**s for 5 and 10GHz, currently using book "RF Circuit Design **theory** and Applications, second edition" Reinhold Ludwig, Gene Bogdanov. Also several articles from internet. I did all calculations and cross-checked them with several paper examples.
My current problem is:
1) Final time-consuming step i

I am taking DSP and the instructor explains **theory** but has not shown a single example all semester. One problem on the current homework assignment is to plot the frequency response of a windowed sinc **filter** using a Blackman window. The sample rate is 10 Khz and cutoff frequency is .195. He has given us M= 800. We are suposed to use the FFT instead

Hello I have any question about signal sampling **theory**.
I have signal generated from DDS (10bit with good reconstruction **filter**) , signal is sinus of known frequency 100 kHz.
I need to know as precisely as possible amplitude and time zero crossing
I have 12bit ADC with 5 MSPS (STM32F303).
i.e. 50 samples per period or 1 sample/7,2 degree.

I am using this circuit. As DC bus I am applying currently 30V and at output I am able to achieve a sine wave by further employing a **filter** Circuit
In **theory** what should be the peak output voltage of the sine wave???? Shouldn't it be +30V
I am getting a peak of +12.5V and 25V p-p.

i have two basic questions
1) why control systems are low pass **filter**?
2) input of control system is random in nature .But why we are testing the system mostly with step signals.How does the step signal alone completely tell about the system?

Hi everyone,
I am trying to sort out a design that has following line
Pin -> VGA -> gain block -> driver amp -> PA -> **filter** -> directional coupler (coupled signal fed back to VGA control) -> diode PIN switch -> Relay -> Pout
Now problem is that PA can deliver and does deliver 48dBm when **filter** is not in loop but as soon as the (...)

while selecting low pass **filter** for ADC antialiasing, I am confused among different types of active **filter**s like Butterworth, bessel, Sallen-Key etc... .
Please suggest me which one is good.

hi all.
I want to implement normalized subband adaptive **filter** by MATLAB from this book. "Subband Adaptive **filter**ing **theory** and Implementation" by Kong-Aik Lee, Woon-Seng Gan(pages 297-299). I got the e-book version but i don't have the companion CD of [URL="eu.w

Hi all,
Can someone refer me to a site where there's an example of how to code digital **filter**s. I've checked the DSP book by Emmanuel C. Ifeachor and Barrie W. Jervis, but its a lot of **theory** but no practical applications. I want to design a digital **filter** with a sampling frequency of 1.5kHz and cutoff of 6kHz. I'd a

Hi,
I am working on EEG signal. At first i applied the Butterworth Low Pass **filter** to extract 0-64 Hz frequency. Then i applied DWT to extract BETA (16-32Hz) and ALPHA(8-16Hz) wave . So, according to **theory** , 2nd and 3rd level coefficient of DWT should provide the beta and alpha wave. But when i performed the fft of D3 wave i did not get the desir

Dear all,
I have a basic knowledge of signal processing, but unfortunately I'm not a specialist of this field.
I have to build an adaptive MISO (multiple-input single-output) FIR Wiener **filter**, which receives three (or more) signals as inputs and produces an output according to the Wiener **filter** **theory** (for example referring to the book (...)

Matlab (or free GNU Octave) is preferred because it has a strong relation to digital signal processing **theory**. The documentation gives many insights to digital **filter** behaviour and design methods. If you are looking for something "light", you can use any spreadsheet calculator, e.g. MS Excel to simulate a digital **filter** in time domain, (...)

See this like starting idea
It will hardly implement the 50/60 Hz frequency conversion.
Generally speaking, the hardware of a typical single phase motor inverter is what you need:
Input rectifier, bus capacitor, PWM controlled H-bridge, output inductor, possibly a sine **filter**.
If high input power factor is required, the AC/

singboon,
Regarding your comment on power supply **filter**s performing without the aid of a series resistor: The formula for cutoff frequency depending on a series resistor is based on linear circuit **theory**. A power supply **filter** has highly non-linear circuit element(s), the diode(s). In this case, the capacitor is used strictly as an (...)
