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.
For the network shown in Figure, find the current delivered by the 10-V source and the voltage across the 3- resistor by means of mesh-current analysis.
A symmetrical fluctuating message, with |f(t)| max = 6.3 V and KCR = 3, is to be encoded by using an encoder that employs an 8-bit natural binary code to encode 256 voltage levels
I need I circuit that calculates f(n) = 2^2^n, where n is a 4bit number. I tried with a decoder but unsuccessfully.
