Astables (AQA A-Level Physics): Flashcards

Continuous pulses of fixed frequency and duration

No stable states - constantly switches on/off

$t_p = t_{on} + t_{off}$

$\frac{1}{t_p}$

$\frac{t_{on}}{t_p} \times 100$

$\frac{M}{S}$

RC network + NOT gate with hysteresis

$\frac{2}{3} V_s$

$\frac{1}{3} V_s$

$1.4 RC$
