AMPLITUDE MODULATION AND DEMODULATION : OBJECTIVE : Study how to perform the amplitude modulation and demodulation and to calculate the modulation index for various modulating voltages. Theory : AMPLITUDE MODULATION : Modulation is defined as the process by which some characteristics of a carrier signal is varied in accordance with a modulating signal. The base band signal is referred to as the modulating signal and the output of the modulation process is called as the modulation signal. Amplitude

Fear Induced Emotion on Motivation University of Texas at Arlington Anxiety is a psychological‚ physiological‚ and behavior state in humans and animals by a threat to well-being or survival‚ either potential or actual. Each of us has felt afraid‚ and we can all recognize fear in many animal species. The function state of fear is defined in terms of being caused by a particular pattern of adaptive behavior to avoid or cope with that threat. We have all been in a situation where we are in fear

pain and can vary quite substantially from one individual to another. As patients are managed and treated for symptoms they are often at some point referred for spinal diagnostic imaging such as X-rays‚ CT scans and MRI’s. The diagnostic imaging modality will very often demonstrate commonly encountered findings associated with degenerative disc disease. As the results become available to patients‚ care providers‚ legal counsel and Insurance carriers‚ it raises questions with regards to the relationship

Simple Stimulus Learning Lauren N. Jones Psychology 550 February 28‚ 2011 Dr. Rachel Needle Simple Stimulus Learning “Stimulus learning is a relatively permanent change in behavior‚ or behavior repertoire which occurs as a result of experience” (Terry‚ 2009). Since there is no possible way to observe knowledge itself‚ behaviors are our only source of observing what has taken place concerning learning. Learning is an inclusion of the potential for change in behavior. This change in behavior

Emotion –induced blindness Introduction Emotional visual scenes are powerful attracters of attention. Evidence suggests that emotional stimuli themselves attract attention‚ and they can disrupt perception of subsequent stimuli (Anderson and Phelps‚ 2001). In a visual attention search task‚ faster reaction time has been found when target is an emotional stimulus than neutral stimuli (Ohman‚ Lundqvist‚ & Esteves‚ 2001). From these result it seems that emotional stimuli enhance perception of such

How do skin receptors’ distribution change one’s reaction to pain in different areas of your body? Aim: Our senses are responsible for receiving information in the outside environment and sending it to our central nervous system‚ where this information is then interpreted. Organs such as the skin‚ known as sense organs‚ have specific neurons named receptors‚ which are each responsible for responding to specific types of stimulus. The receptors responsible for identifying our sense of touch are distributed

1) Amplitude Shift keying (ASK) ASK is a modulation technique that related with amplitude of carrier wave being altered or modulated by information signal. When binary ‘1’ is appeared‚ the signal is transmitted and it is stopped when binary ‘0’ is appeared. The binary ‘0’ and ‘1’ are represented the shifting value between the two selected amplitude. 2) Frequency Shift Keying (FSK) FSK is a modulation technique that related with the frequency shifting or changes of carrier signal to transmit the

If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2.
