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 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
To accurately measure the frequency in hertz (Hz) of a signal or waveform, one can use an oscilloscope or a frequency counter. These devices can analyze the signal and provide a numerical value for its frequency in hertz.
An oscilloscope or a frequency counter can be used to measure frequency. Oscilloscopes display the waveform of a signal and can measure its frequency, while frequency counters directly count the number of signal cycles per second to determine frequency.
A carrier wave is produced by an electronic oscillator that generates a steady waveform at a specific frequency. This waveform serves as the base signal on which information is modulated for transmission in communication systems like radio and television. The carrier wave's frequency determines the bandwidth and reception quality of the transmitted signal.
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.
A: FM means frequency Modulation meaning the frequency remain the same. pulse modulation the frequency can vary
Just the amplitude change, while the frequency and phase still remain

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.
The waveform obtained typically represents the variation of a signal over time, illustrating its amplitude and frequency characteristics. Depending on the nature of the signal, it can exhibit various shapes such as sinusoidal, square, or triangular forms. Each waveform conveys specific information about the signal's behavior, including its periodicity and harmonics. Analyzing these waveforms is essential in fields like audio processing, telecommunications, and electrical engineering for understanding and manipulating signals.
Waveform amplitude refers to the strength or magnitude of the signal. It represents the maximum displacement of the waveform from its baseline. In essence, amplitude reflects the loudness or intensity of the signal being represented by the waveform.
This is called the Laplace transform and inverse Laplace transform.
