ezmsg.sigproc.digitize#

Digitize floating point signal data into signed integer samples.

Functions

digitize(min_val, max_val, dtype=DigitizeDType.INT16)[source]#

Digitize floating point signal data into a signed integer dtype.

Parameters:

min_val (float) – Input value that maps to the minimum representable value of dtype.
max_val (float) – Input value that maps to the maximum representable value of dtype.
dtype (str | DigitizeDType) – Signed integer output dtype: "int16", "int32", or "int64".

Returns:

DigitizeTransformer.

Return type:

DigitizeTransformer
