Unique Codes for each channel 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. Resistance Opposition to direct current Ω (ohm) Current flow affected by cable length. Resistance is present in battery-powered circuits. Impedance Opposition to alternating current (AC) Z Current flow is affected by frequency, cable length, induction, and capacitance. Impedance is present in AC-powered circuits.

Orthogonal Frequency Division Multiplexing (OFDM) Transmission technique used with wireless devices that use the 5-GHz radio band and can achieve a data rate as high as 54 Mbps. It divides the allotted frequency into channels similar to frequency hopping and direct sequencing. Digital. Dense Wavelength Division Multiplexing (DWDM) An optical multiplexing technology that allows several different streams of data to travel down the same optical fiber simultaneously. Frequency Division Multiplexing (FDM) Divides the available bandwidth into frequency bands, and each band is used for a different communication channel. Analog or Digital. Which multiplexing technique transmits each signal from one input source via a single time slot through the creation of different slots? Synchronous Time Division Multiplexing Which category of multiplexing randomly allocates time slots to different data signals depending on the rate at which they are being generated from the source? Asynchronous Time-Division Multiplexing A company is developing a television network to broadcast local news content using analog signals.Which multiplexing technique should be used?
