Introduction
A multiplexer is a crucial digital circuit that is capable of selecting a single digital signal out of a set or group of signal at its input and passes that signal to its output. It functions as a more as a rotary switch that switches connects one input to the output at a time. On the other hand, the multiplexer does the exact opposite function; it passes multiple digital signal inputs through one of a set or group of outputs. Through multiplexers, several signals can be sent ...

Summary

This experiment is about the static calibration of a differential pressure transducer. Test measurements are done to find the range of input and output of the transducer, and to determine the “best-fit” line that models how the voltage reading would equate to the real pressure measurement. The input pressure comes from a hydraulic ram with pressure gauge. The output of the differential pressure transducer is in voltage, and is measured by a digital voltmeter. The input pressure is varied from 0 to 6 bar, and the three voltage readings are recorded for each pressure step value.

Introduction

There are various methods that determine the existence of DC-DC voltage conversion. Each method has certain benefits and drawbacks based on the operating conditions and specifications, such as voltage conversion ratio range, the maximal output power, power conversion efficiency, number of components, power density, galvanic separation of input and output and many others. When designing a fully-integrated DC-DC converter, the specifications are relevant; however, some of them gain weight due to the emergence of restrictions. For instance, in the case of IC technology, the options and availability of the ...

Abstract

An ontology refers to a formal, common, shared description of significance concepts within a specific domain. Ontologies can be used to support various tasks in diverse areas of research such as information retrieval, knowledge management, databases, natural language processing, “geographic information systems”, digital libraries, “multi agent systems” or “visual information retrieval systems”. An ontology makes it possible to have shared knowledge as well as reuse where there can be communicating of information resources between software and human agents. However, ontologies have conceptually been in development since the 1970’s and in the late 1990s’-early 2000’s, we began seeing languages ...

ABSTRACT
In an LRC circuit where a resistor, capacitor and inductor are connected in series is an example of a resonant circuit. Such a circuit can be tuned in order to achieve resonance. At resonance the phase angle of the input voltage in the circuit is zero. When an AC input voltage is applied to such a circuit the phase angle will be affected since the impedance of the capacitor and inductor are dependent on the frequency of the input voltage. For this experiment the phase difference between voltage and current for components in a series LRC resonant circuit. ...

Abstract

An operational amplifier – OP-AMP is a circuit device that amplifies buffers or attenuates the input signal depending on the configuration. Amplified signal means that the output is greater than the input. This means the gain is larger than one. A buffered output means that the magnitude of input is equal to the output; only that the input has been delayed. An attenuated signal implies that the gain magnitude is less than unity. In this paper, amplification using an op-amp will be investigated. Inverting and non-inverting configurations will be connected and tested. Input waveforms and output waveforms will be compared. It ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...

Discussion:

Using the measurements made in the procedure, calculate the quiescent current IE, and the internal emitter resistance re.
The quiescent current IE and internal emitter resistance re can be calculated using the DC analysis carried out in Step#1 and Step#2 of the procedure. The DC voltage measured across RE is used to measure the biasing current across the emitter of BJT. The voltage is measured to be 793mV. Since RE = 1KΩ, so:
IE=VERE=0.7931000=0.000793A=0.793mA.

Now, we can calculate the internal resistance of emitter using the formula provided in the procedure. So:

re=0.026IE=0.0260.000793=32.786Ω

Using the values obtained in the experiment; draw the small-signal ac equivalent circuit for the amplifier.
