can someone help me do this and maybe also the picture of the scope explain how you get it. thankyou! Frequency-sh...
hi can you help me solve this question?..thank you.. A Quadrature Phase Shift Keying (QPSK) modulator has a carrier frequency of (b) 10GHz is used to send data at a rate of 500Mbps over a satellite communication system. The satellite's transponder has a bandwidth of 300MHZ and the measured received signal-to-Gaussian-Noise (power) ratio at the receiving ground satellite is 30dB. If the satellite signal is equalized to have an equivalent raised cosine filter characteristic, determine the transponder's: roll-off factor )...
Can you please help me answer Task 2.b? Please show all work. fs=44100; no_pts=8192; t=([0:no_pts-1]')/fs; y1=sin(2*pi*1000*t); figure; plot(t,y1); xlabel('t (second)') ylabel('y(t)') axis([0,.004,-1.2,1.2]) % constrain axis so you can actually see the wave sound(y1,fs); % play sound using windows driver. %% % Check the frequency domain signal. fr is the frequency vector and f1 is the magnitude of F{y1}. fr=([0:no_pts-1]')/no_pts*fs; %in Hz fr=fr(1:no_pts/2); % single-sided spectrum f1=abs(fft(y1)); % compute fft f1=f1(1:no_pts/2)/fs; %% % F is the continuous time Fourier.

signals and communications 2 Make sure you show all working and describe each step in your calculations. 1. A signum function is defined as sgn(t) = { 1、12 0 1 t<0 Plot and express this function in terms of the unit-step function. 5 marks/ Determine and plot the even and odd parts of the signal 2. x(t) (te-3 +2)u(t). 5 marks 3. If prove that y[n-m] = x[n-m] * h[n]. 5 marks 4. Assuming α > 0, plot the signal...
