Parameters

integer required
Target channel
allowed values:
Moku:Lab1, 2
Moku:Go1, 2
Moku:Pro1, 2, 3, 4
Moku:Delta1, 2, 3, 4
number required
Desired sample rate
allowed values:
Moku:Lab15.63MHz, 7.813MHz, 3.906MHz, 1.953MHz, 976.6kHz, 488.3kHz, 244.1kHz, 122.1kHz
Moku:Go3.906MHz, 1.953MHz, 976.6kHz, 488.3kHz, 244.1kHz, 122.1kHz, 61.04kHz, 30.52kHz
Moku:Pro39.06MHz, 19.53MHz, 9.766MHz, 4.883MHz, 2.441MHz, 1.221MHz, 610.4kHz, 305.2kHz
Moku:Delta39.06MHz, 19.53MHz, 9.766MHz, 4.883MHz, 2.441MHz, 1.221MHz, 610.4kHz, 305.2kHz
units: Hz
number
Coefficient or tap count
default: 201
string
Filter shape
default: Lowpass
allowed values:Lowpass, Highpass, Bandpass, Bandstop
number
Low corner frequency. The low_corner is expressed as a fraction of the sample rate. For instance, if the sample rate is 3.906 MHz and the low_corner value is 0.1, the resulting low corner frequency is 390.6 kHz.
default: undefined
allowed values:0.0001 to 0.49
number
High corner frequency. The high_corner is expressed as a fraction of the sample rate. For instance, if the sample rate is 3.906 MHz and the high_corner value is 0.1, the resulting high corner frequency is 390.6 kHz.
default: undefined
allowed values:0.0001 to 0.49
string
Window function
default: None
allowed values:None, Bartlett, Hann, Hamming, Blackman, Nuttall, Tukey, Kaiser
integer
Window width (Only when window function is Tukey)
default: 50
integer
Beta/Order for kaiser window (Only when window function is Kaiser)
default: 7
boolean
Disable all implicit conversions and coercions.
default: true
