TOPIC 3: ASTABLE MODE











                                     OUTPUT WAVEFORM










































                                         Figure 3.2 : Output waveforms of Astable Mode





                 Figure 3.2 shows the Astable Mode output waveform at pin 3 in a square
                 wave.  The  capacitor  voltage  waveform  is  shown  at  pin  2.  During  the

                 output  timer  is  in  Time  Low  (TL)  state,  the  capacitor,  C  is  discharging
                 through resistor RB starting from 2/3 Vcc to 1/3 Vcc. Meanwhile, during

                 the output timer is in Time High (TH) state, the capacitor, C is charging
                 through resistor RA and RB from 1/3 Vcc to 2/3 Vcc.
