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.
A radar systemuses pulses of duration D tomodulate the amplitude of a radio carrierwave. The system can distinguish between targets spaced apart by a distance of d ≥ cD, where c is
Design a logic circuit when to provide an output when any two or three of four switches are closed.
POP PSW Instruction It is similar to above pop instruction but instead of normal register pairs it uses PSW as its operand. Program status word comprises of the content
Define Magnetic field The area around a magnet is known as the magnetic field and it is in this area that the effects of the magnetic force formed by the magnet can be detected
SUB Subtract Instruction This instruction is used to subtract the contents of any register or memory location from the contents of accumulator. There are two formats as
Professional engineers engage with a wide range of technically advanced and complex problem. So technical know-how is necessary to solve problems, advance existing technologies and
One byte Instructions One byte instruction include both the opcode operand in the same byte. To identify one byte instruction one must observe followings things .
Q. Define waves and transmission lines? In basic circuit theory we neglect the effects of the finite time of transit of changes in current and voltage and the finite distances
Program Description In the above program any two numbers can be stored in register A and B ( by replacing XX and YY). Contents of B are compared with A. If B CY = 0
