- %% Transfer function of a RC-network
- % This script will run automated measurements for you. Note that all frequencies
- % are given in Hertz.
- %% Component Values
- % Fill in the measured values in the following code box.
- %%
- R = 3.2942e3; %Ohm
- C = 315.82e-9;%Farad
- %%
- % Give the desired begin and end frequency as well as number of steps:
-
- f_start = 10; %Hz
- f_stop = 1e3; %Hz
- %%
- % Do not edit the following code box.
-
- f = 10.^linspace(log10(f_start),log10(f_stop),500);
- %% Theoratical Curves
- % Give the equations for the magnitude:
- %%
- A = -10*log10(1+(2*pi*f*R*C).^2);
- %%
- % For the phase:
-
- P = -atan(2*pi*f*R*C);
- %%
- % For the cut-off frequency:
-
- Fc = 1/(2*pi*R*C);
- %%
- % And both asymptotes where $f >> f_c$ and $f << f_c$:
-
- S_smaller = 0*f; %smaller than cut-off frequency
- S_larger = -20*log10(2*pi*f*R*C); %larger than cut-off frequency
- %% Running the Measurement
