What is conduction angle and how can we measure it. I am using
Microelectronics by Sedra Smith 5e. I am not clear about this concept
and couldn't find any resource on the web also.
Kindly explain it to me.
Thanks in advance!

Consider that each full cycle of a sinusoidal waveform may
be considered as "360 degrees" of that wave.

With that established, the fraction of the wave period in
which a given active device is conducting (or otherwise
doing its thing, e.g., amplifying the signal) may be expressed
in terms of degrees. For instance, if you pass a sinusoid
through an ideal (no forward drop) diode, you could say that
the diode (since it passes exactly half the wave) has a
"conduction angle" of 180 degrees.
