Explain isolated I/O scheme.
In I/O mapped I/O scheme the addresses allocated to memory locations can also be assigned to I/O devices. Because the same address may be assigned to an I/O device or a memory location, the microprocessor should issue a signal to distinguish when the address on the address bus is for an I/O device or a memory location.
Q. Write a short note on the frequency response of a R-C coupled amplifier. At low frequencies ( , the reactance of coupling capacitor Cc is quite high and hence very small pa
A three-phase transposed line is composed of one ACSR conductor per phase with flat horizontal spacing of 11 meters as shown in Figure (a). The conductors have a diameter of 3.625
Q. Give an account on the operation of the R-C coupled amplifie r. When a.c. signal is applied to the base of the first transistor, it appears in the amplified form across its c
Give three reasons why a chamfer shouldn't be considered an "unimportant" dimension. When conducting an audit, what is the first step and what is its purpose? Why will calcul
Memory location 2000H has the word 5000H stored in it. What does each location contain after DEC WORD PTR [2000H].
Q. Evaluate complex power in power system? The complex power ¯S in a single-phase systemis the complex sum of the real (P) and reactive (Q) power, expressed as follows:
A transistor has (A) One p-n junction. (B) Two p-n junction. (C) Four p-n junction. (D) Five p-n junction. Ans: A transistor has two p-n junctions.
Q. Explain the significance of the Coupling capacitor and the RE - CE circuit. The function of the coupling capacitor is to isolate the amplifier input circuit from the source.
Q. Define wireless communications? The latest wireless communications technology is the personal satellite phone. The coverage is planetary and one can reach anywhere on earth.
Electric field strength: When two metal plates are charged and divided in a certain distance, a potential difference will exists among the plates. A force was also generated
