Given the relaxation oscillator of Fig. 17.69:
a. Find RBl and RB2 at IE = 0 A.
b. Determine VP, the voltage necessary to turn on the UJT.
c. Determine whether R1 is within the permissible range of values defined by Eq. (17.8).
d. Determine the frequency of oscillation if RB1 = 200 ( during the discharge phase.
e. Sketch the waveform of vc for two full cycles.
f. Sketch the waveform of vR2 for two full cycles.
g. Determine the frequency using Eq. (17.17) and compare to the value determined in part (d). Account for any major differences.
