1. (8 pts.) If the circuit needs to generate a periodic output signal ($v_o$) with frequency of about 120 kHz,
and that is roughly 'high' 60% of the time and 'low' 40% of the time, which of the below components
would you pick for $R_a$, $R_b$, and C. You may use a component value more than once. Show the details
of your calculations for full credit.
