2. 2.

   How many RC sections are used to achieve a 180° phase shift?

   Hint

   Consider how multiple sections contribute to phase.

3. 3.

   What is the total phase shift required for the oscillation to occur?

   • 90°
   • 180°
   • 360°

   Hint

   Consider the sum of contributions from different components.

4. 4.

   The output of the RC Phase Shift Oscillator is a:

   • True (Sine Wave)
   • False (Square Wave)

   Hint

   What type of waveform is typically desired in audio applications?

5. 5.

   Design an RC Phase Shift Oscillator circuit that operates at a frequency of 1 kHz. Calculate the required values of R and C.

   Hint

   Recall the relationship between frequency and the product of RC.

6. 6.

   Explain how changing the frequency response of the oscillator might impact its application in audio equipment.

   Hint

   Think about how sound waves need to resonate at certain frequencies.
