Hi ,
I am trying to design comb generator of 30 MHz to 1 GHz using multisim 12.0. I got the **impulse** **response** but its amplitude is decreasing as the frequency increases as shown in figure attached. What can i do to get smooth comb like output in spectrum analyzer?

At the final expression of H(s), the exponential has -s*T1 which represents a delay.
**impulse** **response**=1 from 0 to T1 and then 0 from T1 to infinity.
Step **response** = linear ramp from 0 to T1 and then is T1 from T1 to infinity.

I have a signal cos(w0 * t). It is sampled at frequency f_s. The samples are applied to a moving average filter of length L. I want to find the amplitude of the output.
So far I understand the following. Please do correct me if I am wrong; I am still learning the basics.
DTFT of **impulse** **response** of the moving average filter: H(w) = (1/L) * (1 -

Hi,
I simulated a UWB vivaldi antenna in HFSS. I would export S11 as .csv file from HFSS and import it in MATLAB.
The purpose is to find out **impulse** **response** h(t) of UWB antenna.
After importing .csv file of s11 from HFSS, what I need to perform to get **impulse** **response** h(t) of that antenna?
Thanks

Hi i have attached an image of a simple low-pass filter. To the left of the image the **impulse** **response** is something decreasing in time, while the **impulse** **response** in the right is in the sinc function. I can understand the sinc function since the input **impulse** is a rectangular waveform which is made up of (...)

So say i want to input a **impulse** signal to my systems then my input is nothing but a rectangular waveform???
Am i correct about this???Correct.
You have to consider mainlobe of Spectrum.
Spectrum of Rectangular waveform is Sinc function.
Mainlobe of Spectrum has to be far wider than bandwidth of your system.

There's nothing wrong with the filter. But you see that the second filter still passes part of the unwanted signals. Furthermore, you need to wait at least the threefold time for complete settling of the output signal. Finally there's a relation between the length of the **impulse** **response** (Fs*filter order) and the minimal achievable bandwidth.

Hi,
Is there a block in virtuoso where I can input the time domain **impulse** to get the required characteristics? The reason why I am asking is because I am trying to model an optical channel which has a gaussian **impulse** **response** and modeling the transfer function using svcvs is a bit tedious. I have the time domain **impulse** (...)

A Linear Time-Invariant system with **impulse** **response** h1h1 is an ideal lowpass filter with cutoff frequency ωc=π/2ωc=π/2. The frequency **response** of the system is H1(ejω)H1(ejω). Suppose a new LTI system with **impulse** **response** h2h2 is obtained from h1h1 by (...)

Convolution is used when your system has the following two properties
1 Linear Time Invariant: The output of the system does not change if you apply same input at another time. If your input is combination of inputs like x1 + x2 then the output should also be the sum of two individual outputs y1 + y2.
2 Finite **impulse** **response**: If you apply an im

Hi,
I am little confused about channel propagation of a wireless waveform.
I know that
y= h*x + n -------- in time domain
Y=HX+N --------in frequency domain
where h is the channel **impulse** **response** which can be rayleigh or rician if small scale fading is considered.
But what happens in large scale fading consideration? H t

Hi,
How can I represent the convolution process between a signal comes from Inverse Discrete Wavelet Transform (IDWT) and the channel **impulse** **response**? Is that like the convolution between signal and channel **impulse** **response** in time domain?

Hello,
I'm trying to determine the doppler spectrum for a specific tap, using channel **impulse** **response**.
There is how I proceed to determine the channel **impulse** **response** :
- I have real and imaginary part from ray field E
- magnitude = abs(real + imaginary)
- phase = angle(real + imaginary)
- channel (...)

1. Find the **impulse** **response** of the system by taking the inverse fourier transform of the frequency **response**.
2. Convolute your input with the **impulse** **response**.
Or just use a transient simulation.

The question title involves a contradiction in terms, because a CIC decimator is a filter with finite **impulse** **response** as well.
So more exactly you are asking about using different FIR characteristics than CIC as a decimation filter. The general answer is quite simple, if you want a different frequency characteristic than (sin(x)/x)^n, you won't

Hi everyone,
After somme researchs on the web, I don't find the answer of my problem (or I don't understand it) and I hope this post will succeed.
I'm working on a real-time FFT convolution algorithm (C++) which split the **impulse** **response** in several increasing size blocks (64/128/256/...).
To realise the convolution, I have to split the incomi

All basic signals have specific purpose
**impulse** -used to get frequency **response** of system
step- used to get time **response** of system and it also used to extract some portion of signal
signum-?
ramp-?
my i knowthat use or application of above two signals.Thank you in advance.

Hi all,
I am trying to implement STTC-OFDM (2Tx-1Rx) over frequency selective channels(2-taps or 3-taps and so on). I need a modification on my code over single tap quasistatic flat fading environment. My question is how can I use the channel **impulse** **response** for multiple tap channels on the maximum likelihood decoder to calculate branc metrics.
