We offer Study of Hybrid Parameters of A Transistor, HP-01 the following studies can be carried out with this set-up: Study of h11 parameter (input impendance parameter). Study of h22 parameter (output admittance parameter). Study of h21 parameter (forward current transfer ratio). Study of h12 parameter (reverse voltage feedback ratio). The experimental set-up is provided with a built-in power supplied and is complete. The set-up is so designed that no high voltage is exposed and hence safe in handling by the students.
