Hi,
I want to know how to draw the frequency response of Raised Cosine Filter (using the equation https://en.wikipedia.org/wiki/Raised-cosine_filter ) in MATLAB.
I tried to implement the equation in MATLAB but I am not successful in getting the expected result.
Can any one please help me...
Thanks FvM for your quick reply.
That's my problem. I am a beginner and I don't know know how to implement square root logic.
My inputs are 14-bits in 2.12 format.
If squared, then they become 28 bits each. And then a square root has to be applied. I am bit confused in determining the...
Hi,
I am interested in knowing how the absolute value of a complex number can be found using digital logic design.
I know that abs(x+iy) = sqrt(x^2 + y^2).
Is there any easy way to implement it in Verilog or VHDL?
Hi,
I am new to Digital Communications and MATLAB. I am learning to implement modulations and demodulations in MATLAB.
I have an amplitude modulated signal at the receiver input. I am trying to recover the message bits after the demodulation.
Following are the parameters of the modulated...
For example, y(t) = A cos(w_n * t)
Hilbert( y(t) ) => applying -90 degree phase shift (exp(-j*pi/2)) to the positive frequency components and +90 degree phase shift (exp(j*pi/2)) to the negative frequency components.
y(t) can be rewritten as, y(t) = A cos(w_n * t)...
