  Apollo Subcarrier Oscillator (SCO) Demodulator

  Recovers analog sensor voltages (0-5V) from FM subcarrier oscillators used
  in FM downlink mode. The spacecraft PMP generates 9 SCO channels encoding
  analog telemetry as frequency deviations of +/-7.5% around each channel's
  center frequency.

  SCO Channels:
    1: 14,500 Hz    4: 40,000 Hz    7: 95,000 Hz
    2: 22,000 Hz    5: 52,500 Hz    8: 125,000 Hz
    3: 30,000 Hz    6: 70,000 Hz    9: 165,000 Hz

  Only valid in FM downlink mode (not PM mode).

  Parameters:
    sco_number: SCO channel number (1-9)
    sample_rate: Input sample rate in Hz (default 5.12 MHz)
