24. In full duplex, transmission signals are transmitted in only one direction; one station is the transmitter and the other is the receiver 25. A reduction in strength as signal is transmitted from source to destination is referred to attenuation 26. In simplex communication, transmission signals are transmitted in both directions. 27. The peak amplitude is the maximum value or strength of the signal over time; typically, this value is measured in volts. 28. The Spectrum...
