question:Recall that the RC filter has transfer function: H(f) = . For frequencies ranging from f = - 200 KHz to 200 KHz, with R = 10 K W and C = 1 m F, plot the magnitude and phase angle for the transfer function, on one plot, with the left vertical axis showing H(f), and the right vertical axis showing the phase angle, in radians .
MY answer:
C=(1/10).^6; H=(1./(1+(j*2*f*R*C)));
>> plotyy(f,abs(H),f,angle(H)); grid;
>> R=10000;
>> f=[(-200)*10.^3: 50000: (200)*10.^3];
>> C=(1/10).^6; H=(1./(1+(j*2*f*R*C)));
>> plotyy(f,abs(H),f,angle(H)); grid; xlabel('frequency');

C=(1/10).^6;
grid;
R=10000;
f=(-200)*10.^3: 50000: (200)*10.^3;
C=(1/10).^6;
H=(1./(1+(j*2*f*R*C)));
H=((1./(1+(j*2*f*R*C))));
yyaxis left
plot(f,abs(H))
hold on
yyaxis right
plot(f,angle(H))
xlabel('frequency');
