TOPIC 3: ASTABLE MODE









               4. Calculate the time high (TH), time low (TL) and frequency of output

                   from Astable mode timer.


































               Answer:




               TH = 0.693 (RA + RB) C1
                     = 0.693 (5KΩ + 2KΩ) (10uF)

                     = 48.51ms



               TL= 0.693 (RB)(C1)

                   = 0.693 (2KΩ) (10uF)

                   = 13.86ms



               Frequency = 1 / (TH + TL)
                                 = 1 / (48.51ms + 13.86ms)

                                 = 16.03Hz
