36.1.4. Transfer Function and its Poles

Try these first

1. 1.

   What does the transfer function represent in circuit analysis?

   Hint

   Think about how outputs relate to inputs in our analysis.

2. 2.

   What happens to the output signal at frequencies below the cutoff frequency?

   Hint

   Recall the behavior of filters.

3. 3.

   What does a pole in a transfer function indicate?

   • A value that affects the numerator
   • A value that makes the denominator zero
   • A design choice in amplifiers

   Hint

   Think about the definitions we discussed related to transfer functions.

4. 4.

   True or False? The cutoff frequency can be determined by the values of R and C in an R-C circuit.

   • True
   • False

   Hint

   Recall the formula for cutoff frequency.

5. 5.

   Given a series of R and C values, design a high-pass filter and calculate the cutoff frequency. Explain how changing the resistance impacts this frequency.

   Hint

   Use the cutoff formula, consider the roles of R and C.

6. 6.

   Analyze how both R-C and C-R filter behaviors differ in a Bode plot and note the importance of the poles in shaping the curves.

   Hint

   Refer back to the characteristics discussed regarding poles.
