A transistor has low input impedance and high output impedance and hence the use of Z and Y parameters becomes Ã‚Â 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 Ã‚Â and high impedance of the transistor. Another Ã‚Â 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 Ã‚Â 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.
