The length of a phasor represents the amplitude.
Amplitude is the maximum value of a voltage or current.
The duty cycle of a pulse waveform with a pulse width ofµs and a period ofµs is 25%.
A ramp is the type of waveform characterized by a non-linear increase or decrease in voltage or current.
A 1 kHz signal has a period of 1 ms.
The angular position of a phasor represents the angle of the sine wave with respect to a reference.
The instantaneous value is the voltage or current value of a waveform at its peak.
The designation rms means repetitions measured per second.
Duty cycle is the characteristic of a pulse waveform that indicates the high time versus the low time.
The unit of frequency is the hertz.
Periodic is characterized by a repetition at fixed time intervals.
Average value of a sine wave is 0.times the peak value.
Two series resistors are connected to an ac source. If there are 7.5 V rms across one resistor and 4.2 V rms across the other, the peak source voltage is
