CONSTRUCTIONAL FEATURES AND CONFIGURATIONS OF SEMICONDUCTOR SWITCHING CIRCUITS
PULSE: The must basic wave form used in digital compyters is called a pulse. The pulse may be defined as a brief surge of voltaor current. The ideal pulse rises instantly from zero to some voltage value, maintains that value over a period of time, then instantly drops to zero.
In practical circuits, the reistance capacitance and inductance, which are always present prevent the attainment f the ideal pulse.
The process of obtaining these waves is called PULSE SHAPING.
RISE TIME: The time required for a pule to increase from 10 to 90 percent of its normal value.
FALL TIME: The time required for a pulse to decrease from 90 to 10 percent of its normal value.
PULSE DURATIONAL: The time during which the pulse is greater than 0.5
OVERSHOOT: The amount of voltage above the pulse’s normal value.
