h parameters-hi,hf,hr,ho parameter

This page covers h parameters which include hi parameter, hf, hr and ho parameter.

h parameters-hi,hf,hr,ho

The depicts h-parameter equation. Using this following parameters are derived which includes hi, hf, hr and ho.

hi parameter

hi = (V1/I1)|V2=0
hi is input impedance with output shorted

hf parameter

hf = (I2/I1)|V2=0
hf is short circuit current gain

hr parameter

hr = (V1/V2)|I1=0
hr is reverse voltage amplification with input open circuited

ho parameter

ho = (I2/V2)|I1=0
ho is Output Admittance with input open circuited
