Experiment 1: Use the design equations (21) to (25) to compute the component values for the experiment. Build the circuit in Fig. 9 to meet the following requirements: A. Design a pulse generator for frequencies = 15 KHz, 10 KHz, and 5 KHz with a 70% duty cycle. Use C -9.4 nF. B. For frequency = 10 kHz, generate the waveform for the following duty cycles: 90%, 70%, 50%, 30%, and 10%. Display the output signal. Explain if the output is what you expected. Questions: 1. Were you able to design, build, and test all the circuits to meet the requirement of part (A)? Please explain any discrepancies in your expected and actual results. 2. Were you able to design, build, and test all the circuits to meet the requirement of part (B)? Please explain the issues, if any, you encountered while designing the oscillators for the duty cycles mentioned in the part (B) of the experiment Vcc 8 Vcc charge loc Reset 4 Discharge RST 7 R Q Out Threshold R2 3 S Q 6 Trigger 2 Control G Ground Figure 9: An oscillator based on 555 Timer IC to produce waveforms of different duty cycles.
