Q. Working of Microprocessor Control?
The microprocessor, which has rapidly become a key component in digital control systems, and its associated circuits function as the digital processor. It is often used as a dedicated computer in which the chip itself is programmed to perform specific functions. Digital watches and auto fuel-injection systems are examples. With microprocessor control, not only the same hardware can be used to perform a variety of tasks by reprogramming, but also distributed computation (which results in less expensive and more reliable operation than centralized control) is possible with interconnection and intercommunication of several microprocessors.
Figure shows a block diagram of a microprocessor-controlled dc motor system, in which the controlled process consists of a dc motor, the load, and the power amplifier.
Define Serial In - Parallel Out Shift Registers? For this type of register data bits are entered serially in the same manner as discussed in the last section and the difference
The Maximum clock frequency in 8086 is 5 MHz .

Q. In an RLC series circuit excited by a voltage source v(t), for R = 10 , L = 1 H, and C = 0.1F, determine v(t) if the capacitor voltage vC(t) = 5e -10t V.
Common channel signalling Signalling systems link the variety of switching systems, transmission systems and subscriber equipments in telecommunication network to enable
Q. Explain Resistance-capacitance coupling? It is the most commonly used coupling in discrete device amplifier as it is least expensive and has satisfactory frequency response.
Q. Show the Methods of material handling? Methods of material handling during operations and maintenance activities shall be considered for all facilities to ensure that the fi

Explain the TEST instruction. TEST: The TEST instruction executes the AND operation. The difference is as the AND instruction changes the destination operand, whereas the TEST
In order to demonstrate aliasing, make a plot of the signal x(t) = 3 cos 2π10t - cos 2π30t which approximates a square wave with W = 30 Hz. If the sample points are taken at
