Question 1
A four-stage amplifier system has individual gains of 25, 10, 5, and 2. What is the overall mid-band gain, and discuss how the cascaded nature impacts the bandwidth?
💡 Hint: Focus on multiplication for gain and think about filtering interactions for bandwidth.
Question 2
Given three stages: fL of 10 Hz, 20 Hz, and 40 Hz; fH of 250 kHz, 500 kHz, and 1MHz, find the overall cutoff frequencies.
💡 Hint: Identify extremes in both cutoff frequency groups.
