What is in phase and out of phase?
The phase relationship relates to how the waveforms superimpose in time. For two signals of the same frequency they are in phase when there zero crossing times coincide. When out of phase the zero crossings don't overlap in time.
A signal has a frequency of 100 Hz and a phase of 180 degrees?
The wave has been offset from zero by 0.005 seconds
What are you conclusions about the phase relationship between the driver and the oscillator below and above resonance?
For small frequency of forced oscillation , the phase angle between the forced oscillator and driver is nearly zero . As the driving frequency increases the phase angle increases and is equal is PI/2 ,when both the frequencies (frequency of force and frequency of system for oscillation) are equal. For very large frequency of driver , they are out of phase.
What is meant by free running frequency in phase locked loop?
The VCO is a special type of oscillator that has a frequency controlled by an applied voltage.The frequency of the VCO without any control signal applied is called the free running frequency.
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 mean by stability of the oscillator?
Stability of the oscillator means the how much frequency stability it have. Measure of frequency stability comes from "rate of change of phase w.r.t frequency", the more it is the more stable the oscillator is, because we know that one condition for oscillation is that the loop gain phase shift should be zero, hence if due to ckt. parameters there is some change in phase then by very little variations in frequency we can bring back the loop gain phase shift to zero. ex. is LC tank circuit which act as an osciilator at resonant frequency. Frequency stability can also be measure from quality factor, the higher it is the more stable ckt. is,Parikshit ParasherB-tech ECE, PG power engg.parikshit_parasher@yahoo.co.in
If two waves have same frequency and the same amplitude but opposite phase what is the composite wawes?
If two waves have the same frequency and amplitude but are out of phase by 180 degrees (opposite phase), they will destructively interfere and cancel each other out to produce a composite wave with zero amplitude. This is known as complete destructive interference.
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
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.
What can produce constructive and destructive interference?
Constructive interference occurs when two waves with the same frequency and in phase overlap, leading to a wave with greater amplitude. Destructive interference occurs when two waves with the same frequency and opposite phase overlap, leading to a wave with reduced or zero amplitude.
