I'm running through some old exam papers at the moment and one of the questions are:
The parameter \$h_{oe}\$ is needed to calculate the output impedance of an amplifier. Explain in detail how to measure the parameter \$h_{oe}\$ practically in totality from start to end by using a signal generator and oscilloscope.
I've founf a couple of examples showing how to meazure the output impedance of an amplifier using a signal generator and an osciloscope with a variable resistor such as this example at learnabout-electronics.
In my book they go through an equation where you can get \$h_{oe}=\frac{Z_oR_3}{R_3-Z_o}\$ (This is from a Bootstrapped common emitter ammplifier circuit.) So would you go through the process to find the output impedance abnd then plug the values into the equation above and calculate \$h_{oe}\$?
Update
\$Z_o\$ is the output impedance and \$R_3\$ is the resister between the \$Ecc\$ and the collector which is dynamically in parrallel with the \$R_L\$.
