SECOND-ORDER TIME RESPONSE

SPECIFICATION

Peak Time, Tp
= =

1 − 2 Time required to reach the first/maximum peak

Percentage overshoot, %Mp

− The amount that waveform overshoots from the
% = 1− 2 × 100
steady state or final value

4 3 Settling time, Ts
= @

The time c(t) reaches and stay within ±2% (±5%) of
the steady state value
(±2%) (±5%)

− − Rise Time, Tr
= =

1 − 2 Time required for waveform to go from 0.1 (10%) of
final value to 0.9 (90%) of the final value

1 Delay Time, Td
= Time required for the response to reach 50% of the

2
final value in the first attempt
