Of the remainder the most numerous ICs are analogue-to-digital (and digital-to-analogue) converters and voltage regulators. All of these types togeth

High efficiencies are vital for power amplifiers, not because of the cost of the wasted power itself, but because it produces heat that must be removed, causing inefficient amplifiers not on

AC machines are more widely used than DC machines, but in certain applications DC machines used to be preferred, especially in traction and whenever speed control over a wide range was desired. With the development of high-power semico

AC generators began to be used for the same purpose and the two varieties of electricity supply coexisted for a time, with the advantage perhaps lying with DC generation. The invention by Tesla of the induction motor in 1887 altered the balance d
