Keep all resistors at the same value (i.e. Ri-R-R3-R4). 1.0 0.7 0.5 0.0...
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.
