BISTABLE MULTIVIBRATOR• Requires input trigger to change states• Will stay in last switch state until trigger• Width of the output pulses is determinedby the PRT of the input triggers
BISTABLE MULTIVIBRATOR• Q1 and Q2- transistor switches, alternatelysaturated and cutoff.• R1 and R4 - collector load resistors for Q1and Q2.• R3, R4, and R5 - bias network for Q1.• R1, R2, and R6 - bias network for Q2.
