Kelvins Bridge and Kelvins Double Bridge: When the resistance to be measured is of the order of magnitude of bridge contact and lead resistance, a modified form of Wheatstone's bridge, the Kelvins Bridge is employed.…
CT Scan Working Principle: CT Scan Working Principle - Biomedicine is one area in which the use of digital signal processing techniques had had great impact. Computer tomography A recent advance in diagnostic analysis is…
Construction of Cylindrical Rotor Synchronous Machine: As stated earlier the Cylindrical Rotor Synchronous Machine offers constant permeance to mmf waves irrespective of the mechanical position of the rotor and is, therefore, simpler to model. Figure…
Transformer Substation: The majority of the sub-stations in the power system are concerned with the changing of voltage level of electric supply. These are known as Transformer Substation because transformer is the main component employed…
Types of Encoders in Digital Electronics: By the use of a digital code, it is possible to identify the position of a movable test piece in terms of a binary number. The position is converted…
Steady State Stability of Drive: Equilibrium speed of a motor-load system is obtained when motor torque equals the load torque. Drive will operate in steady-state at this speed, provided it is the speed of stable…
Memory Addressing Modes of 8086: Most of the memory ICs are byte oriented i.e. each memory location can store only one byte of data. The 8086 is a 16-bit microprocessor, it can transfer 16-bit data.…
Pin diagram of 8089 Processor: Pin diagram of 8089 Processor - In a microprocessor-based system, there are many peripheral devices which are interconnected with the main processor as shown in Fig. 9.102(a). To perform any…
Frequency Shift Keying Demodulator Working (FSK): In digital data communication, binary data is transmitted by means of a carrier frequency. It uses two different carrier frequencies for logic 1 and logic 0 states of binary…
Braking of Induction Motor Drive: Following methods are employed for Braking of Induction Motor Drive: Regenerative braking Plugging or reverse voltage braking Dynamic (or rheostatic) braking further categorised as: ac dynamic braking self-excited braking using…
