2.4.2. Week 2: Building Blocks and Signal Amplification

Try these first

1. 1.

   What is the main purpose of an analog circuit?

   Hint

   Think about the 'core' function of analog circuits.

2. 2.

   Define gain in the context of an analog circuit.

   Hint

   It relates to how much stronger the output signal is compared to the input.

3. 3.

   What is the primary function of an analog circuit?

   • A) To convert signals
   • B) To amplify signals
   • C) To process digital signals

   Hint

   Think about what makes analog circuits unique.

4. 4.

   Linearity in analog circuits refers to:

   • True
   • False

   Hint

   Consider if outputs vary directly with the inputs.

5. 5.

   Design a simple circuit that uses a low-pass filter to clean audio signals from a noisy source. Explain your choice of components and configuration.

   Hint

   Consider what a typical audio signal and noise frequency range would be.

6. 6.

   A circuit has a voltage gain of 5. If the input voltage is 1V, what is the output voltage? Additionally, if this circuit has a nonlinear characteristic at extreme inputs, what implications does this have for signal integrity?

   Hint

   Think about how gain affects output and the definition of linearity as you consider distortion.
