The ‘h’ parameter equivalent circuit of a junction transistor

Home » Physical Electronics Devices and ICs » Physical electronics devices and ics miscellaneous » Question

The ‘h’ parameter equivalent circuit of a junction transistor is valid for—

1. High frequency, large signal operation
2. High frequency, small signal operation
3. Low frequency, small signal operation
4. Low frequency, large signal operation

Correct Option: C

The ‘h’ parameter equivalent circuit of a junction transistor is valid for low frequency, small signal operation only. Hence alternative (C) is the correct answer.
