Laboratory No 4 Electrical Systems 100 AC CIRCUITS INTRODUCTION The purpose of this laboratory test was to make comparisons between theoretical and practical results and to develop a greater understanding of factors affecting the operation of complex AC networks. SUMMARY OF RESULTS The error in the results ranges from 0.02% to 22.63% and the phase angle errors ranged from 0.02° to 17.27°. This suggests that part of our results were very accurate (series parallel RC network) and the rest

clock at high frequency (Fout=2GHz for example) from an external clock at low frequency (Fref = 100MHz for example). The PLL is also used as a clock recovery circuit to generate a clock signal from a series of bits transmitted in serial without synchronization clock (Figure below). The PLL may also be found in frequency demodulation circuits‚ to transform a frequency varying waveform into a voltage. The PLL uses a high frequency oscillator with varying speed‚ a counter‚ a phase detector and

ABSTRACT This project proposal is of clap switch. A device which can turn on or off any instrument by just clap of a hand. The aim of this project is to demonstrate the idea of clap switch by building a prototype of it. The operation of the circuit is simple. If we clap the lamp turns on and to switch it off clap again. INTRODUCTION With the increasing interest in comfort and luxury and keeping in mind the disable persons a clap switch was invented. A device which can turn on or

"the number of components in integrated circuits had doubled every year from the invention of the integrated circuit in 1958 until 1965 and predicted that the trend would continue "for at least ten years"". and "the 2010 update to the International Technology Roadmap for Semiconductors has growth slowing at the end of 2013

INTRODUCTION Electronics without silicon is unbelievable‚ but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip’s. It has many disadvantages when it is used in power electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors

output.[1]In this configuration‚ an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals.[2] Operational amplifiers had their origins in analog computers‚ where they were used to do mathematical operations in many linear‚ non-linear and frequency-dependent circuits. Characteristics of a circuit using an op-amp are set by external components with little dependence on temperature
