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.
What do you understand by DRAM and its refreshing? Dynamic RAM (DRAM) is fundamentally the same as SRAM, but this retains data for only 2 or 4 ms on an internal capacitor. But
I have a closed loop or feedback system and i want to convert it into electrical circuit. please give me example about this
