Q.1: Part A 2) Sketch and label the waveforms for Vcap and Vout in the astable multivibrator circuit. An astable multivibrator is build using the 74HC14 Schmitt inverter. The values of R,C, and the specifications for the 74HC14 Schmitt inverter when powered from a 6-V supply are given in Table.1. Also, VOH=6V,VOL=0V. 1) Calculate tH1,tL, duty cycle and frequency. 3) If the hysteresis voltage (VT,VT. ) decreases due to a temperature change, what will happen to the output frequency and the output voltage? Answer: Why is a Schmitt trigger inverter used for the astable multivibrator circuit instead of a regular inverter? Explain your answers
