Revision of Basics
Although it is assumed in this book that the reader has enough knowledge of various number systems ( binary, octal and hexadecimal and their relation with decimal number systems) and digital electronics but few important topics are disused in this chapter in brief to revise them as they are useful to understand the working of microprocessor in a better way. For detail knowledge one must refer some books of number systems and digital electronics.
Q. Explain Modulation and sampling? Modulation is the process whereby the amplitude (or another characteristic) of a wave is varied as a function of the instantaneous value of
Q. In a CD amplifier,given Rs =4k?, µ=50 and rd= 35k μ. Find the voltage gain Av. The voltage gain, A v = Vo / V i = µR s / (µ+1) R s + rd = 50*4* (103 )/ (50+1)*4*103
Q. For the low-pass filter configuration of Figure, with R i = R f = 1M, calculate C f such that the 3-dB point is at 1 kHz.
Role of Bureau of Energy Efficiency The role of the Bureau of Energy Efficiency is to: Ready standards and labels of appliances and equipment; Develop a list
Explain Open Loop Control Systems In an open-loop control system, the controller independently computes exact voltage or current required by the actuator to do the job and send

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 someti
in DC series generator we consider Eg=V+Ia(Ra+Rse).But in DC shunt generator why it is only Eg=V+IaRa and not Eg=V+Ia(Ra*Rsh/Ra+Rsh)
A synchronous motor has the following parameters per phase. E=2kv, Eo=5kv, X2=3ohms, and I=700amps. Draw the phasor diagram and determine (a) power angle delta, (b) active po
Q. Explain Continuous-data and discrete-data systems? A continuous-data system is one in which the signals at various parts of the systemare all functions of the continuous-tim
