Challenge Problems
Push your limits with challenges.
Question 1
You are designing a CE amplifier with a necessary cutoff frequency of 1 kHz. Given the relationship between R and C, determine suitable values for R if C = 10ΞΌF.
π‘ Hint: Rearrange the formula to isolate R.
Question 2
A CS amplifier exhibits a phase shift of -90Β° at very low frequencies and approaches 0Β° at high frequencies. Analyze how this behavior impacts signal processing.
π‘ Hint: Consider how shifts can combine or interfere with signals.
