BICSI INSTALLER 2 UPDATED ACTUAL FINAL PAPER
QUESTIONS AND SOLUTIONS RATED A+
✔✔Megabit - ✔✔______- refers to the number of bits of information that can be
transported over the media
✔✔DIGITAL TRANSMISSION
When a device First starts a transmission it will employ a nominal bass voltage of some
level of volts. Example 24 V.
A pulse of +3 V would indicate ______ and the line voltage would rise from 24 V to 27
V.
When the voltage level returns to the 24 V base, it would represent an ________. -
✔✔On state
Off state
✔✔Increase or decrease of three dB will result in what - ✔✔A doubling or we're halving
of the power
✔✔Increases or decreases of 6 dB will cause a doubling or halving of the - ✔✔Voltage
✔✔A gauge change of __ numbers approximately doubles or halves the conductor's
resistance. - ✔✔3
✔✔Resistance - ✔✔Is the property of a conductor to resist the flow of electricity through
it and is expressed in ohms.
✔✔Inductance - ✔✔Is a property of Electromagnetic field built around a conductor that
opposes any change in current flow in a circuit both AC and varying DC.
✔✔Henry - ✔✔The basic unit of inductance is a
✔✔Impedance - ✔✔In AC circuits the total opposition to current flow it's called _______
and is measured in ohms
✔✔Characteristic impedance - ✔✔The input impedance of a uniform analog
transmission lines of infinite length.
✔✔Insertion loss (attenuation) - ✔✔Measured in decibels per unit length at a given
frequency
✔✔Return Loss - ✔✔The amount of reflected energy is affected by the degree of
impedance mismatch between the receiver any transmitter
