what is wrong with my answer?

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');

Edited

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');

where do I put the code in. do I remove my plots?

[madhan ravi]

Yes remove plotyy(f,abs(H),f,angle(H)) and use my code instead

[Kamran Salehi]

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)));

yyaxis left

plot(f,abs(H))

hold on

yyaxis Right;

xlabel('frequency');

I put this and its still giving me errors. it says I have more errors but I don't know why I have errors.

Check edited if it worked make sure to accept the answer
