What Timing circuits means in Physics A-Level, as defined for AQA.
Definition of Timing circuits
Check what you remember
Read the wording for your board, then hide it and explain Timing circuits in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The resistor and capacitor in the timing network set the frequency, so changing them changes the clock rate.
