Quick Reference

A nonrepetitive waveform that rises or falls exponentially from some initial value at some initial time, according to the law y(t) = eat For a > 0 the waveform rises without bound with increasing time t; for a < 0 the waveform decays to zero. One way in which logic signals can become distorted as they travel through a system is for their switching edges to become exponentials, usually due to capacitive loading when the output waveform follows the law v(t) = V(1−exp(−t/CR) where V is the final voltage, R the source resistance, and C the capacitive load.

y(t) = eat

v(t) = V(1−exp(−t/CR)
