Bandwidth
In ___ transmission signals are transmitted in only one direction; one station is the transmitter and the other is the receiver
simplex
The ___ is the maximum value or strength of the signal over time typically; the value is measured in volts
Peak amplitude
The ___ of a signal is the distance occupied by a single cycle
wavelength
A reduction in strength is ___

When signals at different frequencies share the same transmission medium the result may be ___ noise
intermodulation noise
A ___ error can occur in the presence of white noise when a slight random deterioration of the signal to noise ratio is sufficient to confuse the receiver’s decision of a single bit
single-bit
In ___ transmission, each block of data is formatted as a frame that includes a starting and an ending flag.
synchronous
In a(n) ___ there is a cluster of bits in which a number of errors occur, although not necessarily all of the bits in the cluster suffer an error.
error burst
The ___ d(v1, v2) between two n-bit binary sequences v1 and v2 is the number of bits in which v1 and v2 disagree.
