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.
The one line diagram of a simple three-bus power system is shown in the figure below. Each generator is represented by an emf behind the transient reactance. All impedances are e

The advantage of the analog storage oscilloscope is that it has higher bandwidth and writing speed than a digital oscilloscope, being capable of operating speeds of about 15 GHz. T
What is the function of the signal in 8086? BHE signal means Bus High Enable signal. The BHE signal is made low when there is some read or write operation is carried out. i.e.
