Influences on Absolute Precision: Adding capacitance results in coupling with GND, and
therefore noise in GND may adversely affect absolute precision. Be sure to make the connection
to an electrically stable GND such as AV
Care is also required to insure that filter circuits do not communicate with digital signals on the
mounting board, so acting as antennas.
