Introduction to Analog Electronics

Analogue electronics are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term “analogue” describes the proportional relationship between a signal and a voltage or current that represents the signal. An analogue signal uses some attribute of the medium to convey the signal’s information. For example, an aneroid barometer uses the angular position of a needle as the signal to convey the information of changes in atmospheric pressure. Humans experience sound, vision, smell, hearing, or any external physical stimuli in form. In general, the natural physical world is analog. This new book takes the reader from the very basics of analogue electronics to an introduction of state-of-the-art techniques used in the field. This work is intended for people with a general background in electronics and signal processing, who are looking for an introduction to classical electronic solutions employed in measuring instruments involving low frequency analog signal processing.
