Question 1.
What is a gain plot?
Show hintHide hint
Think about how we visualize gain changes.
Question 2.
Define a C-R Circuit.
Show hintHide hint
Consider how this circuit behaves with low frequencies.
3Question 3.
What does a gain plot represent?
- A graphical representation of frequency against time
- An illustration of signal phase shift
- Magnitude of an amplifier's gain versus frequency
Show hintHide hint
What does gain tell us about amplifier performance?
4Question 4.
True or False: A C-R circuit acts as a low-pass filter.
- True
- False
Show hintHide hint
Think about the capacitor's role in filtering frequencies.
Question 5.
Design a simple high-pass filter using a 10kΩ resistor and a 0.01μF capacitor. Calculate the cutoff frequency and explain how this influences audio performance.
Show hintHide hint
Remember the cutoff frequency formula.
Question 6.
Analyze how the gain of an amplifier would be affected by changing the transconductance value from 2 mS to 5 mS, keeping the load resistor constant at 1kΩ. What implications does this have for signal amplification?
Show hintHide hint
Focus on how g affects total voltage across R.
