For the 555 timer (square wave generator) shown in figure 6, assuming the values Vec . 5 v, C-0.1 μF, C'-0.01 μF, Ra 4.7 ko, Rb-10 ΚΩ, answer the following a8). a. Plot the output waveform at pin...
ans, RA = 721.5 kohms, RB = 360.8 kohms, R3 = 3.5kohms as an example solution. Question 7 (6 marks) You have been given a 555 Timer, an LED with Von 2V, a 9V battery that can comfortably supply 5mA of current without loss of voltage, a 1 μF capacitor and access to any resistor values you want. You are to design a circuit that causes the LED to flash periodically once per second with a duty cycle of 75%....
