41.2. Frequency Response Analysis

Try these first

1. 1.

   What happens to a capacitor at low frequencies?

   Hint

   Think about how capacitors behave with low frequency signals.

2. 2.

   Define attenuation in terms of signals.

   Hint

   How does a signal get weaker?

3. 3.

   What is a transfer function?

   • Ratio of input to output
   • Only the output signal
   • Only the input signal

   Hint

   Think how we compare both input and output.

4. 4.

   True or False: Poles can determine the frequency response characteristics.

   • True
   • False

   Hint

   What defines system behavior critically?

5. 5.

   Given the transfer function of an amplifier: H(s) = s/(s^2 + 5s + 6), find the poles and zeros.

   Hint

   Factor the denominator to find the roots.

6. 6.

   Consider a CE amplifier with an input capacitance of 10μF and an output capacitance of 100pF. Analyze its frequency response.

   Hint

   Use cutoff frequency equations to determine the response.
