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.

does wein bridge can be used for frequency measurement? how it is possible?
Merits: 1. It is very simple to shift the operating point anywhere in the active region by just changing the base resistor (R B ). 2. A very small number of compon

why we use delay line in CRO what happens if we not use it?
What is resistivity? Resistivity of a material may be explained as the resistance of the material having unit length and also unit cross sectional area. Unit of it is ohm-m.
