Fig.1. Low pass filter function.
1-1. M file low pass filter and analysis.
The “desolve” command is used to solve the differential equation. i circuit current
v output voltage of the variable circuit “mura” is the coefficients of the
transformation function, and since the transformation function equation is one,
the coefficients s s2 are zero. The den variable is the denominator of the
conversion function. The tf command creates a conversion function. The bode
command is used to draw a bode diagram of the system, that is, the size of the
conversion function in terms of frequency and the phase of the conversion
function in terms of frequency are displayed by the subplot.
i=exp (-1/C/R*t)
Eq.1
V2=R*i
And transfer function is shown in Eq.2:
1/(S+1)
Eq.2
Eq. 1

Fig.2. the output of the filtteer function.
2-1. Display The Final Output.
Display the final output. The result in the “bode” diagram of the sample circuit,
when the phase is drawn in terms of frequency, it can be clearly seen that the lowpass filter passes low frequencies.
