Buffer
A buffer is a logic circuit that amplifies the current or power. Basically it is used change the driving capability of a logical circuit. Therefore it is sometimes referred as drive. A simple buffer and tri state buffers (active high and active and low ) are shown in figure.
A tri state buffer if enabled provided the same logic level of the output as that of input i ,e if input is at logic 1 then it provides logic 1 output.
A moving coil galvanometer consists of a coil in a uniform magnetic field B o, suspended fro a fibre of torque constant C, current I produces a deflection O=nAB o i/c where n is
