One-, Two- and Three-Pole Amplifier Models

The simplest amplifier has

where is a real positive number (corner frequency). There is a single pole at on the negative real axis. This means that the impulse response will decay exponentially without ringing.

If we cascade multiple (three) single-pole amplifiers together

There will still be no oscillation to an impulse.
