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 are the three properties of an analog signal?
Frequency Amplitude Phase from Anura Priyantha
Why sinusoidal signal is called basic signal?
The sinusoidal signal is called a basic signal because, by Fourier Analysis, you can not further reduce it. It is one sine wave of one frequency of one amplitude of one phase. It has no harmonics. If you converted it from time domain to frequency domain you would only get one line, at the fundamental frequency.
Why normalization of message signal is necessary in conventional amplitude modulation?
to maintain the constant frequency and the phase parameters at the output
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 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 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.
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.
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 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.
When a carrier is phase modulated with an integrated modulating signal the resultant is?
It gives frequency modulated signal
Why you go for modulation?
modulating signal is the low frequency signal .so we cant transmit for a long distance.so we go for modulating the signal either by modulating the amplitude or frequency or phase of the signal.
What is effect of frequency drift and phase drift of local oscillator in synchronous detection of dsb sc demodulation?
Frequency drift of the local oscillator can cause distortion and loss of signal in the demodulated output, while phase drift can lead to phase error which affects the accuracy of demodulation in synchronous detection of DSB-SC modulation. Both drifts can introduce errors and reduce the quality of demodulated signal.
What are the parameters of high frequency carrier that may be varied by a lower frequency intelligence?
Following are the 3 parameter by which high Frequency carrier can be varied by low frequency intelligence signal 1) Amplitude 2) Phase 3) Frequency
What cause distortion?
Different frequency components of a signal becoming out of phase
What are the three properties of an analog signal?
Frequency Amplitude Phase from Anura Priyantha
What is the relationship between phase and frequency of a signal?
They are measuring two different things.
