35.4.3. Magnitude and Phase Characteristics

Try these first

1. 1.

   What is frequency response?

   Hint

   Think about the relationship between input and output signals.

2. 2.

   What is the role of capacitors in R-C circuits?

   Hint

   Consider their effect on high vs. low frequencies.

3. 3.

   What describes frequency response?

   • Output behavior to input frequency changes
   • Power consumption
   • Signal distortion

   Hint

   Consider how frequency affects signal processing.

4. 4.

   True or False: A Bode plot uses a logarithmic scale for frequency.

   • True
   • False

   Hint

   Think about how different frequencies are represented on the x-axis.

5. 5.

   Given a transfer function with poles at s = -100 and s = -1000, what are the implications for the frequency response of this system?

   Hint

   Relate pole locations to the typical -3 dB point in filter response.

6. 6.

   You are tasked with designing an amplifier with a specific gain at its cut-off frequency; how would you go about selecting resistor and capacitor values?

   Hint

   Focus on the formula and how altering R and C can move the cut-off frequency.
