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.
Q. A JK flip-flop is shown in Figure (a). (a) Modify it to operate like the D flip-flop of Figure (b). (b) Modify the JK flip-flop to operate like the T flip-flop of Figure (
Explain Noise Noise is unwanted signals which degrade the desired signal content and therefore the performance of the system. Noise might be produced either externally or inte
Sketch the circuit diagram of a 4- ladder network R-C phase shift oscillator and explain its principle of operation. Also determine the gain of the basic amplifier necessary for th
What is extended data output RAM? EDO RAM: A slight modification to the DRAM structure changes the device in an EDO (extended data output) DRAM device. Inside the EDO memory, a
Most ac generators used in Power Stations are of the " Flux Cutting " types. Their effiencies range from less than 33% to slightly more than 60%. In their efficiency equations, the
8 bit data to Register This form of the instruction is used to copy 8 bit data directly to the register location specified in the instruction. The instruction format i
I need help designing a BJT amplifier with that meets the following parameters: voltage gain greater than 300, Ic(Vce=0)=2uA, Vcc=20V.
Q. What do you mean by Instrument transformers? These are generally of two types, potential transformers (PTs) and current transformers (CTs). They are designed in such a way t
Q. Explain state-variable techniques? The matrix formulations associated with state-variable techniques have largely replaced the block-diagram formulations. Computer software
Q. (a) For a JKFFwith JK = 11, the output changes on every clock pulse. The change will be coincident with the clock pulse trailing edge and the flip-flop is said to toggle, when T
