Outline of Each Section

There are three sections below. Each section contains five graphs. Each section corresponds to one test number. The differences between the tests are summarized below.

The five graphs in each section show:

• The baseband signal
• The demodulator output
• The demodulator output with post demodulation lowpass filtering
• The demodulator output with the passband signal clipped at 10% of its real amplitude
• The above with post demodulation lowpass filtering

Summary of Differences Between Tests

• Test Number 9
  • Modulator clock rate of 10 KHz
  • No anti-aliasing filter after modulation or clipping
  • Slew rate corresopnding to 3000 Hz per millisecond
• Test Number 10
  • Modulator clock rate of 40 KHz
  • Anti-aliasing filter after modulation and clipping (sample rate reduced to 10 KHz)
  • Slew rate corresopnding to 3000 Hz per millisecond
• Test Number 11
  • Modulator clock rate of 40 KHz
  • Anti-aliasing filter after modulation and clipping (sample rate reduced to 10 KHz)
  • Slew rate corresopnding to 1000 Hz per millisecond
