Hi,

for my electronics workshop, I compiled a short summary on low- and highpass filters and how they function once they are combined to a bandpass.

Special care was taken in regards to how they are combined (Low + High vs High + Low).

At the end of this document, you will find the complete $\LaTeX$ code to compile the summary for yourself.

##Chain Matrix Highpass $% $

##Chain Matrix Lowpass $% $

##Bandpasses

###Chain Matrix of Highpass followed by Lowpass

###Chain Matrix of Lowpass followed by Highpass

###Chain Matrix of frequency dependent voltage divider

###Note: $K_{TH} \neq K_{HT} \neq K_{ST}$

##$\LaTeX$

This includes pictures of the circuits based on circuitikz.
