Patrick Dziura 03/07/2018 ECE 205 – Siyan Guo Prelab 3 A) Suppose you create the above circuit with R1=R2=1k, and C=.5μF. Sketch the resulting waveform (see page 11 of the TI Datasheet). What will be the period (=1/frequency) of the waveform produced by this circuit? t H = 0.693 * (R 1 + R 2 )*C = 0.693 * (1000 + 1000) * 0.5 * 10 -6 = 0.000693 s = 693 μ s t L = 0.693 * (R 2 )*C = 0.693 * (1000) * 0.5 * 10 -6 = 0.0003465 s = 346.5 μ s The period of the circuit is the sum of t H and t L : Period = 693 + 346.5 = 1039.5 μ s The frequency of the circuit is calculated using the equation below.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
