  Apollo Subcarrier Extractor

  Bandpass filters and translates a subcarrier to complex baseband.
  Reusable for PCM (1.024 MHz) and voice (1.25 MHz) subcarriers.

  Parameters:
    center_freq: Subcarrier center frequency in Hz
    bandwidth: Passband width in Hz
    sample_rate: Input sample rate in Hz
    decimation: Output decimation factor
