36.2. Examining Frequency Response of Amplifiers

Try these first

1. 1.

   What is the frequency response?

   Hint

   Think about how an amplifier changes output with different inputs.

2. 2.

   What is a transfer function?

   Hint

   Consider how we express input-output relationships mathematically.

3. 3.

   What does the corner frequency indicate?

   • The frequency where gain is maximized
   • Where the gain starts to drop
   • The frequency where phase is 0

   Hint

   Consider how gain behaves with frequency.

4. 4.

   True or False: The phase response is constant for all frequencies.

   • True
   • False

   Hint

   Reflect on how phase relates to frequency.

5. 5.

   Design a low-pass filter with a specific corner frequency. Calculate the required resistor and capacitor values.

   Hint

   Consider how varying R and C affects the corner frequency.

6. 6.

   Given a transfer function that includes multiple poles, analyze how to determine its frequency response.

   Hint

   Break down the transfer function to find each pole's individual contribution.
