Microprocessors:
We have learnt 8085 family of microprocessors. Initially, we understand basic components of a computer, 8085 microprocessor architecture and assembly language programming. Then we understand microprocessor I/O and LSI Counters. Specifically we have discussed regarding 8255 PPI and 8253 PIT. ADC and DAC are discussed for and analog and digital interfacing. For serial data communications we have learnt the RS232C standards. Then 2051 Microcontroller is studied to understand the concepts of Microcontroller and how to program them. At last recent trends in microprocessor technology such as 8086, 80286, 80386 and Digital Signal Processors have been investigated.
The property due to which the resistance of some metal or compound vanishes under certain conditions is (A) Semi conductivity. (B) Super conductivity.
Q. Explain working of Common drain amplifie? When an ac signal drives the gate of JFET, it produces an ac drain current. It flows through Rs and produces an ac output voltage t
Q. Data transmission in Bus Topology ? Bus Topology:This topology shares a single path or link way among all users. This common single path way is called bus. In this topology,
Q . Materials that can store electrical energy are called (A) magnetic materials. (B) semi conductors. (C) dielectric materials. (D) super conductors. Ans: C
A moving coil galvanometer consists of a coil in a uniform magnetic field B o, suspended fro a fibre of torque constant C, current I produces a deflection O=nAB o i/c where n is
At the completion of this unit, you will be able to determine the cutoff frequencies and attenuations of RC and RL low- and high-pass filters by using test circuits. UNIT FUNDA
Why are waveguides not used at low frequencies?
Active-mode PNP transistors in circuits: In the figure, the arrows showing current point in the direction of conventional current - the flow of electrons is in the opposite di
(a) Consider the circuit of the noninverting amplifier in Figure, including an ideal op amp. Obtain an expression for the voltage gain of the overall circuit. (b) Let R i = 10
Q. In a 110V compound generator, the armature, shunt and series winding resistance are 0.06?, 25? and 0.04? respectively. The load consists of 200 lamps each rated 55W, 110V conn
