Measuring Transient Response

[laatsch55]

So...
How do we go about this. Is it a measurement of rise time versus gain?

Lee,
I believe that it's better to talk about "transient distorsion"for an audio amp.
Transient response is a generic term related to all systems ( speakers, etc.)
Anyway I have found this " simple " article where is described a measument method
for transient distorsion . I hope it will be helpful for you .

Basically you have to use a square wave generator and measure the odd harmonics ( 3rd and 5th )

Be more specific ...

I don't believe a standard measurement method exists. Certainly slew rate will limit transient response, but slew is a steady state measurement. Peak transient power, for example, might be an interesting thing to measure. Find a pulse generator and set duty cycle to 10% and time interval to 0.5 seconds. Measure voltage across an 8 ohm load with an oscilloscope, and turn up the amplitude until the pulse doesn't get any taller. Scope can be externally triggered by the pulse generator's trigger output to make it easier to see and measure.

Transients respond in odd ways when alcohol is introduced into the circuit, but I'm just sayin'.

Can you tell me more info about peak transient power and about test arrangment ?
Thank you in advance .
