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.
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 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 is the relationship between phase and frequency of a signal?
They are measuring two different things.
What are the three properties of an analog signal?
Frequency Amplitude Phase from Anura Priyantha
What features of the ASK signal suggests that it's an AM signal?
Just the amplitude change, while the frequency and phase still remain
Why sinusoidal signal is called basic signal?
