This is a design circuit for modulated current that is provided by the integrated rotational speed sensor KMI 15/x. This current signal must be converted to ground referenced voltage signal, matching the logic levels of the processing unit for digital signal processing. This signal conditioning can be done by using this circuit. This circuit is consists of protective elements to suppress line conducted interference and low pass filter in front of the comparator input. This is the figure of the circuit;

This circuit uses first-order RC low pass filter as signal filter. This circuit is made of C4 and R3 with cut off frequency of 10 kHz. This cut off frequency is used to achieve an optimum absorption of noise.

Components of the above is one component of ic which is applied as a reinforcement. Power amplifier used in an audio signal in order to become more powerful and can be heard via a tool that is the speaker. But in each set must have a voice amplifier, voltage, power quality is different.
For the IC has the output power above 2 X 40 Watt with 8 Ohm output impedance. Supply voltage ranging from 18 Volt to 32 Volt.
