As shown, 555 and RP1, RP2, C1 compose the controllable multivibrator, its oscillation frequency depends on the constant time of R1, RP1, RP2, C1. But the oscillation depends on the voltage level of the input gate wave. When the Vln is high voltage level, VT1 is saturatedand conducted, the 4 foot of 555 is low voltage level,force the 555 resets, with no output; When the VlnO is low voltage level, VT1 closes, 555 is in a state of free oscillation, its 3 foot outputs the sequence oscillationsquare wave.
