•Measures each point in a single cycle of a signal relative to its point of origin
Phase tells you the delay in a signal
repetition rate of signal
It gives frequency modulated signal
AC if the signal is of the same amplitude but out of phase yes the net product Vs time will be zero.
When a circuit is said to be resonate it means a signal or wave that is being generated has some relationship with a reflected or feedback signal such that the generated signal is reinforced with the reflected or feedback signal. This reinforcing of the signal may cause a standing wave of constructive interference and required the generation of the signal and the reflection or feed back to be in phase or Coherent. if there is no phase coherency then it can be harder to achieve the standing wave of constructive interference. However is the Phase is detected and delay is compensated it can be achieved like in a laser ring gyro, which uses two resonate cavities that have there path length adapted to cope with heat expiation.
Following are the 3 parameter by which high Frequency carrier can be varied by low frequency intelligence signal 1) Amplitude 2) Phase 3) Frequency
Amplitude Frequency
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
One of the best phase constant calculators available for determining the phase constant of a signal is the Phase Constant Calculator tool provided by MathWorks, which is widely used in the field of signal processing and engineering.
An ADPLL is an all-digital phase locked loop - a control system that generates an output signal whose phase is related to the phase of an input signal.
The formula for calculating the phase of a signal in a communication system is phase arctan(imaginary part / real part).
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
Baud rate is the measure of how many times per second a signal makes a transition between two different states. The state of the signal can be a measurement of frequency, voltages, or phase angles to name a few. The Baud defines the number of signal events that occur in a transmitted signal.
repetition rate of signal
what is phase modulation changing of the phase depending upon the modulated signal is said to be a phase modulation
Phase modulation and frequency modulation are related because changes in the phase of a signal result in corresponding changes in its frequency. When the phase of a signal is modulated, it causes variations in the frequency of the signal as well. Therefore, in practice, it is difficult to separate phase modulation from frequency modulation, especially in communication systems where both aspects are interconnected.
It gives frequency modulated signal
The amplitude of a signal is the measure of the maximum magnitude of the signal from its equilibrium value. It represents the strength or intensity of the signal. A higher amplitude indicates a stronger signal, while a lower amplitude indicates a weaker signal.
