  1. 1. In PWM, this feature of the pulse represents the voltage of the audio signal.
  2. 3. A ramp generator has negative feedback via this component
  3. 4. The switching levels of the Schmitt trigger determines this feature of the triangle wave
  4. 5. A ramp generator will continue to increase or decrease its output until it reaches saturation.
  5. 9. A Schmitt trigger has this many switching levels
  6. 10. One input to the comparator in PWM is this type of wave.
  7. 11. A Schmitt trigger has an op-amp with this type of feedback
  8. 12. This is constant for the pulses in PWM
  9. 14. If a ramp generator has a positive voltage at the input, then the output voltage will do this
  10. 15. PWM can be demodulated using a treble cut ...

  1. 2. The ramp rate is proportional to the size of the voltage here.
  2. 3. The op amp in PWM behaves as one of these
  3. 6. This is constant for the pulses in PWM
  4. 7. The time period of the triangle wave depends on the ramp _______ of the ramp generator.
  5. 8. To form a triangle wave generator, the output of the ramp generator connects to the input of the Schmitt ...
  6. 13. One input to the comparator in PWM is from the audio ...
  7. 16. The frequency of the triangle wave must be at least _______ the highest audio signal frequency so that it is sampled correctly.
