Multivibrators and 555 Timer - Technical MCQs

Q1:

Design a circuit using a 74121 to convert a 33-kHz, 30% duty cycle waveform to a 33-kHz, 60% duty cycle waveform.

A Rint = 2 k, Cext = 0.012 nF

B Rint = 2 k, Cext = 0.012 F

C Rint = 4 k, Cext = 0.012 nF

D Rint = 4 k, Cext = 0.012 F

ANS:B - Rint = 2 k, Cext = 0.012 F
