True or False

Mark each of the statements below True or False.

1 .       Amplitude is the maximum value of a voltage or current. [Hint]

 
 


2 .       Average value of a sine wave is 0.707 times the peak value. [Hint]

 
 


3 .       Duty cycle is the characteristic of a pulse waveform that indicates the high time versus the low time. [Hint]

 
 


4 .       The unit of frequency is the hertz. [Hint]

 
 


5 .       The instantaneous value is the voltage or current value of a waveform at its peak. [Hint]

 
 


6 .       The designation rms means repetitions measured per second. [Hint]

 
 


7 .       Periodic is characterized by a repetition at fixed-time intervals. [Hint]

 
 


8 .       A ramp is the type of waveform characterized by a non-linear increase or decrease in voltage or current. [Hint]

 
 


9 .       A 1 kHz signal has a period of 1 ms. [Hint]

 
 


10 .       The duty cycle of a pulse waveform with a pulse width of 10 µs and a period of 100 µs is 25 %. [Hint]
