Being unable to design the oscillator to meet all the requirements of part (B) of experiment 1, you sought help from a colleague who is heading out to attend a meeting. Your colleague takes a quick look at your design (equations, circuit diagram etc.) and suggests the resistance in the charging path is always larger than the resistance in the discharging path, which prevents you from meeting some of the duty cycle requirements. He then suggests a quick solution Switch the resistances in the charging and discharging paths, which would allow you to make the resistance in the charging path less than the resistance in the discharge path (see circuit in Fig. 10). You can then build the oscillator to meet the missing duty cycle requirements. He further suggests doing the math again to make sure everything adds up. You decide to follow your colleague's suggestion but do the theoretical analysis and the design implementation in parallel. Questions: 1. Were you able to build the oscillator to generate the waveforms for the remaining duty cycles? Either way explains why the circuit behaved the way it did. 2. Do the new/modified design equations meet the duty cycle requirements? Either way, explain why or why not.
