Challenge Problems
Push your limits with advanced challenges
Given two input signals with amplitudes 2V and 0.5V; calculate the differential mode output if the gain is 15.
💡 Hint: Use Output = Gain * (Differential Signal) formula.
If a signal has a common mode gain of 0.05 and a differential gain of 30; what can be concluded about the noise levels in high-frequency applications?
💡 Hint: Consider how low gain impacts the effectiveness in reducing noise.
