Fibre Optics in Medicine and Communication Review Questions with complete Solutions Graded A+
Fibre Optics - Answers Technology that uses thin glass or plastic fibers to transmit light signals
Total Internal Reflection - Answers When a light ray is reflected back into the medium it came from
Refractive Index - Answers Measure of how much a ray of light bends when it passes from one medium
to another
Endoscope - Answers Device used in medical physics to view the interior passageways of the human
body
Cladding - Answers Material wrapped around the fibre bundle to control refractive indices and reduce
energy losses
Analog Signal - Answers Continuous wave with fluctuations in amplitude and frequency
Digital Signal - Answers Signal represented in discrete values, either 'on' or 'off'
Bandwidth - Answers Range of frequencies used in transferring data, higher bandwidth allows for more
information
Analog-to-Digital Converter (ADC) - Answers Device that converts analog signals to digital signals
Digital-to-Analog Converter (DAC) - Answers Device that converts digital signals to analog signals
Pulse Code Modulation (PCM) - Answers Method used in ADC to convert analog signals to digital signals
Sampling - Answers Stage in PCM where variation of data is gathered into discrete time signals
Quantization - Answers Stage in PCM where amplitudes of sampled data are rounded off and
represented in binary form
Encoding - Answers Stage in PCM where each value is converted at specified time intervals
Resolution - Answers Smallest output increment that a DAC can produce
Conversion Time - Answers Time from input code application until output stabilizes around final value
Reference Value - Answers Highest voltage that a DAC can reach
Transmission Quality - Answers Measure of how well a signal is transmitted without distortion or loss
Data Storage - Answers Method of storing data, either in wave form or binary bit form
Power Consumption - Answers Amount of power used by a device or system
Transmission Rate - Answers Speed at which data is transmitted
