-if the period of one cycle of an AC signal is 20mS what is its frequency?
50 cycles
What is the pulse width duration of a 500-hz digital signal if the duty cycle is 20 percent?
4ms
Is the signal with zero frequency a periodic signal?
No, because for a signal to become periodic it must repeat itself in regular intervals of its time period.A 0 Hz signal has a time period equal to infinity , so technically the signal can never complete a full cycle by reaching infinity let alone repeat itself, since the signal is unable to repeat itself in regular intervals its not periodic.
The frequency of this signal is?
If you are given a graph of the signal. Calculate the period, T, which length of time for one cycle. The frequency is f = 1/T (Hz) For example. T = 20 ms, f = 1/(20 ms) = 50 Hz. If you are given an equation, in the form of: v(t) = Vm cos (ωt + ϴ) The frequency is ω (rad/s) For example v(t) = 120 V cos ((314 rad / s) t + 0) The frequency is 314 rad/s = 50 Hz.
What does the phase of a signal measure?
•Measures each point in a single cycle of a signal relative to its point of originPhase tells you the delay in a signal
If the duty cycle of a rectangular waveform is 20 percent and the signal is a logic 0 for 40µsec what is the signal frequency?
If the logic 0 is the 20% then the period is 2ms and the frequency is 500 Hz. If the logic 0 is the 80% then the period is 50us and the frequency is 20kHz
-if the period of one cycle of an AC signal is 20mS what is its frequency?
50 cycles
What is the frequency of a signal which has a cycle time of 100 microseconds?
the frequency is 1 divided by the cycle time, or 1/100 microseconds = 10,000 cycles per second
The time it takes to complete one cycle of a signal is known as?
The time it takes to complete one cycle of a signal is called one period. For example, if the signal has a frequency of one hertz (one cycle per second), the period would be 1 second. A two hertz frequency would mean a ½ second period, or ½ second to complete one cycle.
What is the frequency?
Frequency is defined as the number of cycles per minute. Ex: for a sine wave from " 0 to pi " is a cycle, and this repeats periodically within a interval of time. if frequency of a signal is 50Hz, then you can say that this signal repeats 50 time's a minute..
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.
What is a measuerment unit for frequency?
The measurement unit for frequency is Hertz (Hz). It represents the number of cycles or oscillations per second of a wave or signal.
If a signal has a frequency of 100 HZ and a phase of 180 degrees how much time has the wave been offset from 0?
The period - the time for one full cycle - is the reciprocal of the frequency. If the frequency is in Hz, the time will be in seconds.From 0 to 180 degrees is one-half of a full cycle.
What is the pulse width duration of a 500-hz digital signal if the duty cycle is 20 percent?
4ms
Why the frequency of a digital signal is infinite?
actually the frequency of a digital signal in infinite because assuming the signal is a square wave for each point in time eg 1 sec the amplitude can remain at max or "dc" for any number of bits assuming 1 bit = dc for 1 sec/clock cycle
What happens to signal's wavelength as its frequency increases?
As the frequency of a signal increases, its wavelength decreases. This is because the speed of propagation of the signal remains constant in a given medium, so as the frequency increases (more cycles per second), each cycle has less distance to cover, resulting in a shorter wavelength.
What is the significance of the 2 pi frequency in the context of signal processing and wave analysis?
The significance of the 2 frequency in signal processing and wave analysis is that it represents one full cycle of a wave. This frequency is important because it helps in understanding and analyzing periodic signals and waves, as well as in calculations involving phase shifts and frequencies.
