A signal has a fundamental frequency of 1000HZ What is its period?
T=1/f T=1/1000 T=1*10-3
What determines Frequency of an AC signal?
A protective relay determines frequency of an AC signal of an electric power system. The protective relay includes a circuit measuring the AC signal period between zero crossings to provide a measured period value. A microprocessor includes a random access memory having a five-element array, which collects five consecutive values of the measured period values. A microprocessor routine chooses a median from the measured period values and generally determines the frequency based upon the median. The median is ignored and the previously determined line cycle period is adjusted to determine the new line cycle period if: an absolute value of a difference between a last value of the measured period values and a previously determined line cycle period is not less than a predetermined value; and the last value of the measured period values is within the limits of the array. <Prof Dae_Pwa>
Which is more reasonable using a sine wave or square wave signal to determine slew rate?
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
-if the period of one cycle of an AC signal is 20mS what is its frequency?
50 cycles
What is pitch period?
The pitch period of a signal is the fundamental period of the signal, or in other words, the time interval on which the signal repeats itself. The pitch frequency is the inverse of the pitch period, which is the fundamental frequency of the signal.
Can discrete signals have fractional periods?
NO . the period of a discrete time periodic signal cannot be in fractions. note that the fundamental period of a discrete time signal is given by. N=m(6.2831/Wo) Where Wo is the fundamental frequency and N and m are integers...

A signal has a fundamental frequency of 1000HZ What is its period?
T=1/f T=1/1000 T=1*10-3
A signal has a fundamental frequency of 1000 Hz what is its period?
The period is the duration of one cycle in a repeating event, so the period T is the reciprocal of the frequency f. T = 1 / f. The period is 0.001 second, that is 1 millisecond.
How do you find the fundamental frequency of a sample using a spectrum analyzer?
Looking at the spectrum displayed on the spectrum analyzer, the fundamental will generally be the left-most vertical spike above 0Hz. However, to qualify as the fundamental, this tone must have a specific harmonic relationship to the other components of the sampled signal. The relationship is that every upper tone in the signal should be an integer-multiple of the frequency of the fundamental. Thus, if you find three spikes, one at 200Hz, one at 300Hz and one at 400Hz, the 200Hz tone is not the fundamental. That would be a tone at 100Hz, and the signal you are looking at has a 'suppressed fundamental'. Likewise, if the signal described above also had a spike at 50Hz, this _could_ be the fundamental, where the second harmonic (at 100Hz), third harmonic (at 150Hz) fifth harmonic (at 250Hz) and all harmonics above the sixth are being suppressed. An additional worthy test is to turn off the signal and look at the spectrum. If there are signal components displayed that don't relate to the sample, they would show up after the signal is removed. (I.e., do an analysis of silence, and anything that shows up needs to be subtracted or discounted from the signal spectrum.)
How does tracking devices work?
by broadcasting a radio signal. The signal is picked up by a minimum of 3 satellites, which by triangulation can determine where the signal is coming from.
What are three important characteristics of a periodic signal?
Period (or frequency), amplitude and phase. All periodic signals can be broken down into other signals... most commonly sine/cosine waves, but there are others too. These components will each have their own frequency, amplitude and phase that combine into the original signal. The strange part of the question is the phase. A signal on it's own does not have a phase unless you provide some reference signal to compare it to. Generally, this comparison signal is implied by the context of your particular situation. When you decompose a periodic signal into components, however, it is almost always implied that the phase of each component is in reference to the fundamental component (So the fundamental has phase 0, while the others have phases referenced to that). This is done specifically so that each component will combine to create the original signal.
The frequency of a signal is inversely proportional to what?
period
How find time period of discreet signal?
To find the time period of a discrete signal, you need to identify the time interval between consecutive occurrences of a specific pattern or value in the signal. This may involve observing the repeating pattern in the signal and measuring the time it takes for the pattern to repeat. Once you have identified this time interval, it represents the time period of the discrete signal.
I cant get signal on my phone after I dropped it?
You will need to take your phone into your service provider to determine why it doesn't get signal any longer.
What is the period of a 1000 Hz signal?
The period of a 1000 Hz signal is the time it takes to complete one cycle or revolution of the signal. The formula to calculate the period from the frequency is: T=frac1f where T is the period in seconds and f is the frequency in Hertz. Plugging in the given frequency of 1000 Hz, we get: T=frac11000 T=0.001 Therefore, the period of a 1000 Hz signal is 0.001 seconds or 1 millisecond. This means that one cycle of the signal repeats every 1 millisecond. You can also use this online calculator to convert between frequency and period.
