A multichannel signal refers to a signal that consists of multiple individual channels, each representing a different aspect or component of the overall signal. These channels can be used to convey different types of information simultaneously. On the other hand, a multidimensional signal refers to a signal that has multiple dimensions, with each dimension representing a different characteristic or parameter of the signal. This can include signals that vary in multiple dimensions such as time, frequency, spatial location, or any other relevant parameter.
What the difference between envelop and coherent detection of AM signals
Power vs Signals
now they are better now they are better
It signals the difference between successive sample sizes
A copper cable transports electrical signals. An optical cable transports light signals.
d. Modem It modulates digital signals to analogue signals and demodulates analogue signals back to digital signals.
In in- bandsignalling , the control and management signals travles along with the data signals where as in out of band signalling the data and control signals travels in different channels
The difference between satellite tv service and cable is satellite tv offers more channels and are more expenisve. No, they don't receive their signals from a satellite.
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
Energy signals have finite energy over time, meaning that the total energy is finite. Power signals have finite power over time, meaning that the average power is finite. Energy signals have zero power; power signals have infinite energy.
A phase difference between two periodic signals is the time difference between two corresponding points on each signal. This time difference is usually measured in degrees or radians, but can be given as a unit of time as well.
