What does mono phase mean in electrical engineering?
mono phase probably means that you're using a linear phase response filter or delay meaning that all your frequency components get the same delay. Think of a square wave in the frequency domain, and how delay of reactive systems are a function of frequency
What are three basic components of all signals?
•Amplitude-Height (loudness) of the wave-Measured in decibels (dB)•Frequency:-Number of waves that pass in a second-Measured in Hertz (cycles/second)-Wavelength, the length of the wave from crest to crest, is related to frequency•Phase:-Refers to the point in each wave cycle at which the wave begins (measured in degrees)-(For example, changing a wave's cycle from crest to trough corresponds to a 180 degree phase shift).
Why does the frequency domain better than the spatial domain?
we can use frequency domain for finding phase of the input signal and magnitud of the instrument. we can use frequency domain for finding phase of the input signal and magnitud of the instrument.
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.
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.
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.
Need of frequency domain response instead of time domain?
The frequency domain shows the frequency-time behavior. You can measure this with a spectrum analyzer. Meaning you can see parameters like bandwidth and phase. This is useful for several applications like servo control, audio, RF. You can choose servo parameters by looking at bandwidth and phase margin so you can choose parameters like gain and Pd so you have a safe margin where the phase gets inverted (30 deg is a practical value).The time domain shows you what actually happens with a signal in time. An oscilloscope for example can be used. It is handy for measuring single events, pulses etc. In applications like servo control you can see what the final result of the design is, the overshoot and settling time.
How Phase modulation and frequency modulation are inseparable?
both are related because phase is an integral function of frequency
What would be the 3 phase voltage on a frequency of 50 Hz?
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
Unit to measured phase is?
unit to measure phase is degree
What is the difference between phase and frequency?
No matter what frequency, there are 360 degrees that can be associated with it (the phase). Here's an equation to summarize: V(t) = A sin ([w*t] + p) A is amplitude w = frequency p = phase shift
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.
