Lab Report: Common Emitter Amplifier

Introduction

A laboratory was conducted to evaluate the characteristics of a common emitter amplifier. The configuration is a bipolar-junction-transistor (BJT). Transistors allow current to flow from positive to negative states or from negative to positive states. A transistor board was supplied for the experiment. Five activities were done during the lab: a DC analysis, An AC analysis gain at midband (with bypass capacitor in circuit), AC analysis gain at midband (with no ...

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.

In this part, we will draw the small scale ...

Abstract

Schizophrenia is a psychotic disorder characterized by distortion of reality, disturbances of thought and language, and withdrawal from social contact. It can also result in cognitive disturbances. Cerebellar dysfunction, movement problems, and postural control are also among important problems of schizophrenia. Various factors are involved in the development of schizophrenia. In these factors, hereditary characteristics, environment, and brain structure and function are found to have an important role. Medical imaging techniques such as positron emission tomography (PET), diffusion tensor imaging (DTI), and magnetic resonance imaging (MRI) can help in studying the disease. This paper deals with some important aspects of ...

Genetics has contributed greatly to the evolutionary changes within both plant and animal kingdom. It has been characterized with several systems that helps achieve greater evolutionary changes. Segregation distortion is one of those systems, helping to create powerful evolutionary forces which forms the basis of genetics and inheritance within the living organisms. The mechanism of the segregation distortion simply acts of the law of segregation which states that allele pairs either separate or segregate during the formation of gamete or uniting randomly during fertilization.
The segregation of sorghum is a form of evolutionary forces that is now used to ...

ANALYSIS REPORT

Major thesis and position of author: The two argue that, to leave people to be driven in their self-interest without control and some following their luck and inheritance to own means of production will eventually reduce everyone who is not advantaged, into virtual slavery. This way, only a few will be happy but the majority will live in misery.
1. Briefly state in your own words three facts presented:
Capitalism has been proven by many analysts to be the sole reason that has led to the crumbling down of many economies in the world. Secondly, it has also ...

Multi-driver speaker systems require ‘Crossovers’ as their subsystems and are primarily used for the separation of input signal on the basis of driver into various different frequency ranges. The power which is received by the drivers is only in their usable frequency range and therefore the distortion which is caused in the drivers can be reduced with the use of crossovers. Crossovers are only helpful in order to minimize the distortion and it is not possible to completely block at the passband edges, similarly amplitude variation and face changes also cannot be completely restricted.
Crossovers are primarily of ...

Introduction
Being a marketing manager at Lacoste, the marketing director requested a report to be prepared that describes the interlocking components of the attitudes that influence relationships between consumers’ attitudes and behaviors. In addition, the report tries to discuss some of the factors that may influence the purchasing of footwear.
According to Hoyer and Macinnis (2009), consumer behavior reflects the totality of the consumers’ decision with respect to the attainment, consumption, and nature of goods, services activities, experiences, people and ideas by human decision-making units.

Problem Statement

The main issue the report tries to illustrate is the factors that influence the ...
