CONFIDENCE VOTES 57
consider a two port network. if u take the ratio of output of one port either current or voltage/ input of other port either voltage or current, if it is same parameter ie. V2/V1 then we call it as transfer function or gain also. V1 is the input port voltage and V2 is the output port voltage. In s domain also we can call it as transfer function, and also not necessary restricted to s-domain only. Suppose if is of different parameter ie. I1/V2 we can call it as reverse transfer admittance function but thing is to note the presence of 'transfer' term. At the same time the ratio of parameter current or voltage of the same port we call it as driving point function. It can be Admittance function ie. I1/V1 or Impedance function ie. V1/I1

Answer 2

Difference between Driving point and Transfer point function

• In two port system input is taken at one port and yield is taken at other port. For two port system on the off chance that proportion of voltage to current is taken at same port, at that point it is called driving-point impedance.

• The transfer qualities is of following sort:  

• the ratio of 1 voltage to other voltage or voltage transfer ratio.  
• the ratio of 1 current to other current or current transfer ratio.
• the ratio of 1 current to other voltage or transfer admittance.  
• the ratio of 1 voltage to other current of transfer impedance.
