Detailed Description

Component with a predefined transfer function turning it into a high-pass filter.

It's probably better if time_const_output is of the same order as dt.

Todo:

Investigate the influence of time_const_output. Should I rather set it to dt, such that dt/time_const=1?

Constructor & Destructor Documentation

def CompoundPye.src.Components.highpass_filter.HighpassFilter.__init__	(		self,
			time_const_RC,
			time_const_output,
			debug = False
	)

Initializes a HighpassFilter object.

Parameters

time_const_RC	Time constant as in an electrical high-pass filter.
dt	Based on wikipedia's description of a high-pass filter, the time-step dt is required for the transfer function.
debug	Set False, if you don't want to see debugging output, set True if you want to see debugging output.

Member Function Documentation

def CompoundPye.src.Components.highpass_filter.HighpassFilter.update	(		self,
			input,
			dt
	)

Updates the Component.

Similar to Component.update, but it additionally requires to store the current value in HighpassFilter.input_pre.
