If the frequency of a rectangular waveform is 20 kHz and it is logic 1 for 30µsec. What is the duty cycle of the waveform and How long does the signal remain a logic 0?

The period of a 20 kHz waveform is 1 / 20 kHz, or 50 uS. If the waveform is logic 1 for 30 uS, then it is logic 0 of 20 uS, and the duty cycle is 60%.
Simply subtract from 30 from 50 to get 20. Also, compare 30 against 50 to get 60%

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
What is a cycloconverter?
A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
What is the relationshipo between frequencies ampilitude and waveform?
wave length is inversly proportional to the frequency of the same wave. i.e, if the wavelength of the signal is too large then frequency will be decreased.
How do you differentiate FM from PM signal?
A: FM means frequency Modulation meaning the frequency remain the same. pulse modulation the frequency can vary
What features of the ASK signal suggests that it's an AM signal?
Just the amplitude change, while the frequency and phase still remain
Draw the waveform of AM signal and DSBSC signal?
Draw thewaveform of AM signal and DSBSV
What mathematical process can you use to transform signal waveform of frequency domain into time domain. or the other way around?
This is called the Laplace transform and inverse Laplace transform.
How does the signal change at the output AM out?
Your question doesn't give enough detail. AM typically stands for amplitude modulation. It is how AM radio works. A constant frequency is transmitted and the amplitude is varied to modulate the carrier wave with an information signal such as a song. Hence if you were examining how an AM signal changed you would see changes in the peak-to-peak voltage of the carrier frequency waveform.
What feature of the ask suggests that it's an AM signal?
Just the amplitude change, while the frequency and phase still remain
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.
Which signal types are represented by a continuous waveform?
Analog
Why are analog waveforms sampled 8000 times every second?
The frequency range for a voice signal is 300 to 4000 HZ. The Nyquist theorem states a waveform should be sampled at 2 times its highest frequency. So 2 x 4000 is 8000 samples every second. This ensures an adequate representation of the signal.
