It gives frequency modulated signal
Is Magnitudes of two waves are same but phase difference is zero?
AC if the signal is of the same amplitude but out of phase yes the net product Vs time will be zero.
What is the difference between a resonant and a non-resonant circuit?
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.
What are the parameters of high frequency carrier that may be varied by a lower frequency intelligence?

In phase modulation the amount of phase shift in the carrier signal depends on the of the modulating signal and the rate of phase shift depends on the of the modulating signal?
Amplitude Frequency
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
What is meant by zero phase frequency how it affects the signal?
Zero phase frequency refers to the frequency at which the phase shift of a signal is zero, meaning that the output signal is in perfect alignment with the input signal. This concept is crucial in signal processing, particularly in filtering, as it ensures that the signal's timing and amplitude remain intact. When a signal is processed at zero phase frequency, there is no distortion or delay introduced, preserving the signal's integrity. Deviations from this frequency can introduce phase shifts that alter the timing and shape of the signal, potentially leading to unwanted effects.
What is the best phase constant calculator available for determining the phase constant of a signal?
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.
What is an ADPLL?
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.
What is the formula for calculating the phase of a signal in a communication system?
The formula for calculating the phase of a signal in a communication system is phase arctan(imaginary part / real part).
What is the difference between frequency modulation and phase modulation?
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.
What is the difference between baud and baud rate?
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.
What is matlab code to detect phase error in ofdm signal?
To detect phase error in an OFDM signal using MATLAB, you can estimate the phase using the received signal and compare it to the expected phase of the transmitted symbols. Here's a simple example code snippet: % Assume 'received' is your received OFDM signal and 'transmitted' is the original signal phaseError = angle(received) - angle(transmitted); % Normalize phase error to be within [-pi, pi] phaseError = mod(phaseError + pi, 2*pi) - pi; This code calculates the phase error for each symbol in the received signal by taking the difference between the angles of the received and transmitted signals.
What does frequency of a signal measure?
repetition rate of signal
Application of signals and systems?
what is phase modulation changing of the phase depending upon the modulated signal is said to be a phase modulation
How Phase modulation and frequency modulation are inseparable?
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.
