    If you have one large system (System A) which includes several sub-systems (Sub-Sys 1-6) like this:



    Say that all the sub systems have their own unique input impedance and output impedance. They also have a unique voltage gain in dB.

    How do you work out the input/output impedance and end-to-end gain for the ENTIRE system, ie the gain, input impedance and output impedance of System A?


    ANY help would be massively appreciated :confused:

    Input impedance is purely what the input signal sees when entering the input of the system. Therefore it is based only on the input impedance of the first sub-system. Same with output impedance, based only on the last in-line subsystem. If the gain of all subsystems are in DB's, simply add them together.
