8 Questions
What is the fundamental frequency of a signal?
The frequency at which all frequency components of a signal are integer multiples of one frequency
In a graph with the horizontal axis as time, what does the graph display?
The value of a signal at a given point in space as a function of time
What is the absolute bandwidth of a signal?
The width of the spectrum of a signal
What does the period of the total signal equal to?
The period of the fundamental frequency
What does effective bandwidth (or just bandwidth) refer to?
The narrow band of frequencies that most of the signal’s energy is contained in
What does data rate measure in a communication system?
The rate at which data can be communicated in bits per second
What is the primary function of bandwidth in a communication system?
To constrain the bandwidth of the transmitted signal based on the transmitter and transmission medium
What does error rate indicate in a communication system?
The rate at which errors occur during the transmission
Test your knowledge on signal graphs with time as the horizontal axis and fundamental frequency concepts. Assess your understanding of how graphs display the value of a signal at a given point in time as a function of distance and the definition of fundamental frequency.
