https://doi.org/10.1057/9780230100664The purpose of this section of the measurement system is to receive the signal after transmission through the channel, to amplify it if necessary and to perform any signal conditioning needed before data display. We must first examine the basic amplifier circuits in common use.

Power Supplies and their Applications,Chapter 4 has shown that although electrical energy is commonly distributed in alternating current (a.c.) form, local supplies of direct current (d.c.) are often required for motors. Other common applications for d.c. are electroplating and battery charging.

The Transducer and Transmitter,The transducer in a measurement system converts variations of the measured variable into an electrical signal. The transmitter then converts the signal into an electrical form suitable for transmission through the channel. Except when using electromagnetic waves (radio) as a channel, the transmitter is often an integral part of the transducer.

Data Display, was largely limited to analogue or pointer instruments and the cathode-ray oscilloscope. Now however the engineer can make a conscious choice on nearly every occasion and determine whether digital or analogue displays are more appropriate.
