A memory circuit with two stable states. It remains in one state until an external trigger pulse (often added via a differential circuit to the base) forces it to flip.
Transistors are the building blocks for several specialized pulse-generating circuits: Transistors in Pulse Circuits
Used to convert rectangular pulses into sharp, narrow "trigger" pulses by utilizing small time constants ( A memory circuit with two stable states
The "deep" logic of a transistor in a pulse circuit relies on transitioning rapidly between two non-linear states: Transistors in Pulse Circuits
The transistor acts as an open switch. Both junctions are reverse-biased, effectively blocking collector current. To reach this state, the base voltage must fall below the threshold (roughly 0.6V0.6 cap V for silicon). 2. Core Pulse Circuit Architectures
