14. What is the Basic principle of ATDM? Variable time intervals
15. What is the Basic principle of CDM? Unique Codes for each channel
16. cyclic redundancy check (CRC) Based on the same principle
for error detection as a parity
check but uses mathematical
algorithms to deter-mine if any
bits are corrupt.
17. Resistance Opposition to direct current
Ω (ohm)
Current floẇ attected by cable
length. Resistance is present in
bat-tery-poẇered circuits.
18. Impedance Opposition to alternating
current (AC)
Z
Current floẇ is attected by
frequen-cy, cable length,
induction, and ca-pacitance.
Impedance is present in AC-
poẇered circuits.
