Filter Modules

passband.low

I/O: signal/signal

Supports HDR: N/A

Parameters:

  • Sample rate (sr): An integer number representing the input sample rate of the modulator. Incongruent input signals will be resampled to this sample rate before any processing occurs within the module. Specified in Hz.
  • Input Channel (id): An integer number greater than or equal to zero. Corresponds to which channel should be used as filter input.
  • Filter order (order): The order of the filter. Determines how sharply the filter culls higher frequencies. Specified as a dimensionless integer greater than or equal to 1.
  • Cutoff frequency (f_c): The cutoff frequency of the filter. Frequencies higher than this will be culled using a Butterworth filter. Specified in Hz.
  • Gain (gain): The output gain of the carrier wave. Defaults to 0.0 dbV.

Notes:

  • Output signal always has one more channel than the input signal. The channel with the highest ID number contains the filtered output.
  • All other output channel contents are identical to their corresponding inputs.

passband.high

I/O: signal/signal

Supports HDR: N/A

Parameters:

  • Sample rate (sr): An integer number representing the input sample rate of the modulator. Incongruent input signals will be resampled to this sample rate before any processing occurs within the module. Specified in Hz.
  • Input Channel (id): An integer number greater than or equal to zero. Corresponds to which channel should be used as filter input.
  • Filter order (order): The order of the filter. Determines how sharply the filter culls lower frequencies. Specified as a dimensionless integer greater than or equal to 1.
  • Cutoff frequency (f_c): The cutoff frequency of the filter. Frequencies lower than this will be culled using a Butterworth filter. Specified in Hz.
  • Gain (gain): The output gain of the carrier wave. Defaults to 0.0 dbV.

Notes:

  • Output signal always has one more channel than the input signal. The channel with the highest ID number contains the filtered output.
  • All other output channel contents are identical to their corresponding inputs.

passband.thru

I/O: signal/signal

Supports HDR: N/A

Parameters:

  • Sample rate (sr): An integer number representing the input sample rate of the modulator. Incongruent input signals will be resampled to this sample rate before any processing occurs within the module. Specified in Hz.
  • Input Channel (id): An integer number greater than or equal to zero. Corresponds to which channel should be used as filter input.
  • Filter order (order): The order of the filter. Determines how sharply the filter culls outer frequencies. Specified as a dimensionless integer greater than or equal to 1.
  • Low frequency cutoff (f_lo): The lower cutoff frequency of the filter. Frequencies higher than this will be culled using a Butterworth filter. Specified in Hz.
  • High frequency cutoff (f_hi): The upper cutoff frequency of the filter. Frequencies lower than this will be culled using a Butterworth filter. Specified in Hz.
  • Gain (gain): The output gain of the carrier wave. Defaults to 0.0 dbV.

Notes:

  • Output signal always has one more channel than the input signal. The channel with the highest ID number contains the filtered output.
  • All other output channel contents are identical to their corresponding inputs.

I/O: signal/signal

Supports HDR: N/A

Parameters:

  • Sample rate (sr): An integer number representing the input sample rate of the modulator. Incongruent input signals will be resampled to this sample rate before any processing occurs within the module. Specified in Hz.
  • Input Channel (id): An integer number greater than or equal to zero. Corresponds to which channel should be used as filter input.
  • Filter order (order): The order of the filter. Determines how sharply the filter culls inner frequencies. Specified as a dimensionless integer greater than or equal to 1.
