    Here are two questions from the past test paper. I do not know how to analysis this kind of circuit. Could anybody help me to solve this two questions? Thanks very much.

    Q1 for the 1st circuit, calculate the UTP,LTP,time for Vo is high,time for Vo is low, and the frequency of the output.

    Q2 for the 2nd circuit, calculate the peak to peak voltage at Va, and the exact value of R1 for an oscillator frequency to be 1.5khz.
  2. t_n_k

    AAC Fanatic!

    Here's a pretty rough solution for the first circuit. Haven't double checked it. Hopefully the ideas are of use in any case.

    You should probably show some attempt at the second.
