WebAn inverted output waveform will lose 1 mark for orientation and be awarded 2 marks for the correct trigger points. (3) 5.3 5.3.1 C 2 and R 3 sets the time period that the circuit will remain in its changed state. (2) 5.3.2 0 V (1) 5.3.3 The moment a positive pulse is applied to the inverting input, the output WebAt nodes 1 and 2, different waveforms are produced. At node 1, a ramping waveform is available and at node 2, a pulsating waveform is available. The slope, and thus frequency of the ramping waveform is controlled by R4 and C1 and depends on the power supply voltage.
