Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design an astable multivibrator circuit for a frequency output of 1 kHz. Specify the component values needed.

💡 Hint: Use the frequency formula F = 1.44 / ((R1 + 2 * R2) * C) to adjust your values.

Challenge 2 Hard

If R2 is set to half the value of R1, derive equations to express the HIGH and LOW time periods based on R1 and C.

💡 Hint: Substitute and simplify using the value ratio.
