2.4.4. Week 4: Frequency Characteristics of Amplifiers

Try these first

1. 1.

   What is the primary purpose of an amplifier?

   Hint

   Think about what amplifiers are commonly used for.

2. 2.

   Define gain in the context of amplifiers.

   Hint

   It's a measure of amplification.

3. 3.

   What is gain typically expressed as?

   • Output/ Input
   • Input/ Output
   • Output - Input

   Hint

   Remember the fundamental definition.

4. 4.

   True or False: Linearity ensures the output accurately reproduces the input waveform.

   • True
   • False

   Hint

   Think about a straight line graph.

5. 5.

   Design a simple circuit that acts as a low-pass filter. Describe its expected frequency response.

   Hint

   Consider selecting resistor and capacitor values that suit your desired cutoff frequency.

6. 6.

   Evaluate why an amplifier designed for a specific frequency range might fail with signals outside that range.

   Hint

   Reflect on how frequency selection affects signal processing.
