MENUMENU

Study of Hybrid Parameters of Transistors HP-01

FEATURES
• Study of h11 parameter (input impedance parameter)
• Study of h22 parameter (output admittance parameter )
• Study of h21 parameter (forward current transfer ratio ).
• Study of h12 parameter (reverse voltage feedback ratio ).
• Built-in power supply

INTRODUCTION
A transistor has low input impedance and high output impedance and hence the use of Z and Y parameters becomes awkward specially at high frequencies. As a result the hybrid of ‘h’ parameters are found to be most useful for transistor circuit analysis, because the hybrid parameters form a and high impedance of the transistor. Another advantage is that the parameters h11 , h21 and h22 almost correspond to the actual operating conditions.
The experimental set-up have been laid down on a decorated bakelite board with an aim of providing an easy understanding to the students. All components are well spread out for clarity and easy repairs and replacement. The set-up is provided with a booklet, which contains its detailed theory of operation, description, specifications, suggestions and discussions on the various experiments that may be performed with it.
