METHOD BY WHICH AN ELECTRICAL RAW INPUT SIGNAL IS RESHAPED TO A FORMATTED ELECTRICAL INPUT SIGNAL ACCORDING TO THE INPUT REQUIREMENTS OF A SIGNAL PROCESSING DEVICE AND A SIGNAL FORMATTING CIRCUITRY

摘要

The inventio concerns a method by which an electrical raw input signal (102) is reshaped to a formatted electrical input signal (104) according to the input requirements of a signal processing device (106). According to the method the following steps are conducted:- feeding a parameter to a programmable device (108) according to the expected raw input signal format in order that,- the programmable device (108) may deliver one or more output control signals (110,111) in dependency of the parameter whereby,- each control signal (110,111) is served at each its switching device (Q10-A; Q10-B) provided in a signal line between the raw input signal (102) and ground potential (114) wherein,- the control signals (110,111) allow switching devices (Q10-A; Q10-B) to connect the raw input signal (102) to ground potential (114) through a resistor of predetermined size (R32, R28), to create the formatted input signal (4) at the resistor (R32, R28).
