Hello friends
the ber formula for the BPSK seems different on the textbooks or i get them wrongfully.
My question is this books seem like using the the ber formula interchangeably as shown above.
these formulas are same?(matlab gives different outcomes)
Hello friends i want to code the average power of quantization error on matlab
the average power is seen below
can you help me how can i do that on matlab
hello friends
i need to generate samples from a pdf function by using inverse transformation method in Matlab.
Could you please help me about the procedure.
Thanks in advance.
hello friends
i want to represent the random binary numbers for binary amplitude shift keying in matlab whose properties as follows.
but i dont know how to represent in matlab
can you help me
Hello friends i am trying to plot the PSD of BASK in MATLAB.
the specifications of the signals as follows:
Number of data bits (1s and 0s) = 100
Sampling frequency fs = 100 Hz
Number of data points (samples) = 100*fs = 10 000 data points
block size of FFT, N = 4096
Bit duration Tb = 1s
Carrier...
hello friends i am currently studying the eye pattern of a baseband data transmission and the an introduction to analog and digital communications book by simon haykin(pages 249-251) gives this example:
in a bandwidth-limited condition if the channel bandwidth is reduce, the eye would close even...
thanks for your reply i actually imitate the code according the matlab website but on the website also magnitudes are very high i.e.(https://www.mathworks.com/help/matlab/math/fourier-transforms.html)
after i divide the magnitude to n it gave me the correct result
could you explain the reason...
Hello friends why matlab gives the magnitude fourier transform of cosine as 250.
is not it should be 1/2 according to the equation below.
thanks

this is the matlab code:
Tsample = 1/50;
t = 0:Tsample:10-Tsample;
x = cos(2*pi*10*t);

Hello friends,
i am trying to plot the PSD of the gaussian noise, to do this firstly i calculate autocorrelation function first then i take the integral of it according the equation below but seems like i get wrong plot(autocorrelation and the psd are the same?). what do you thing i do wrong...
Hello friends,
currently i am studying the problem-based learning in communication systems using matlab and simulink by kwonhue choi and huaping liu,
and the 1d2 1d3 questions asked to sketch autocorrelation and psd functions in simulink,
since i am new in simulink i could not do that can you...
thanks for the reply.
What i want to do is to make sure that both of the collector currents of differential amplifiers are equal to do that i need to change R10 and R11 resistors(potentiometer).However both of the images that i have uploaded at seems like okay in both situation the circuit has...
thanks for your replies the circuit is examined for the wide band amplifier (for school).
Actually my question was about the ltspice simulation.
Did you understand why simulation does not give me the 2.5 and the 7.5 resistance values in the first place?
