Hello,
I'm currently trying to write an integrator for a time domain signal that
does it's work in frequency domain.
An integrator in frequency domain means mainly to multiply the spectrum
with 1/...

I have been given a problem to solve, but I'm having a hard time understanding the syntax and thus also how I'm supposed to solve the problem.
The problem is stated here:

Hello All,
I believe sin (45 deg) and sin (45 radians) will yield different values.
In some literatures, both degress and radians are shown as argument to sine
function (e.g. sin (pi/2) & sin (...

Hello All,
I am trying to understand the concept of representing a discrete periodic
signal using sinusoidal signals.
(without going into detailed math), If my understanding is correct, a
discre...

Hello All,
The classical modulation scheme is defined as,
x(n)*cos(w_0*n) 0.5*[X(w+w_0) + X(ww_0)]  eq(1)
Similarly, text books also define frequency shifting as,
x(n)*exp(j*w_0*n) ...

I am trying to generate a AWGN waveform to add it to the signal of my simul=
ated communication system in MATLAB. The operating bandwidth of the communi=
cation system is about B=3D3GHz and suppose ...
Hi,
I simulate (or want to simulate) an RF system. My simulation Nyquist
rate is 50GHz, the signals are 8 Msamples long and there is a 5MHz
transmission at 1GHz (using standard I/Q modulation).

This is prompted by the discussion of aliasing in the thread
"Higher upsampling with minimum phase downsampling produces
more aliasing" by 'jungledmnc'.
My question is based on the observation th...
