1. Define Cycle ?
ans : A portion of a waveform contained in one period of time.
2. What is Instantaneous value ?
ans : The magnitude of a waveform at any instant of time, denoted by lowercase letters.
3. What is a waveform ?
ans : The path traced by a quantity, plotted as a function of some variable such as positing, time, degrees, temperature, and so on.
4. What is an Alternating waveform ?
ans : A waveform that oscillates above and below a defined reference level.
5. What is a Periodic waveform and What is Phase relationship ?
ans : A waveform that continually repeats itself after a defined time interval. Phase relationship is an indication of which of two waveforms leads or lags the other, and by how many degrees or radians.
6. What is Peak to Peak Value ?
ans : The magnitude of the total swing of a signal from positive to negative peaks. The sum of the absolute values of the positive and negative peak values.
7. What is Peak Value ?
ans : The maximum value of waveform, denoted by uppercase letters.
8. What is Frequency (f) ?
ans : The number of cycles of a periodic waveform that occur in 1 second.
9. What is Average value ?
ans : The level of a waveform defined by the condition that the area enclosed by the curve above this level is exactly equal to the area enclosed by the curve below this level.
10. What is Period (T) ?
ans : The time interval between successive repetitions of a periodic waveform.
