Exponential Signal Descriptors:-
Several of the time descriptors used in digital data communication systems are based on exponential signals. In this problem, we explore three of these descriptors.
(a) The time constant of fall is defined as the time required for a pulse to fall from 70.7% to 26.0% of its maximum value. Assuming that the pulse decreases as e-t/TC, find the relationship between the time constant of fall and the time constant of the exponential decay.
(b) The risetimeof a pulseis the time required for a pulse to rise from 10% to 90% of its maximum value. Assuming that the pulse increases as 1-e-t/TC, find the relationship between rise time and the time constant of the exponential rise.
(c) The leading-edge pulse time is defined as the time at which a pulse rises to 50% ofitsmaximum value. Assuming the pulse increases as 1-e-t/TC, find the relationship betweenleadingedge pulse time and the time constant of the exponential rise.
