2. On a 20 MHz oscilloscope as those used in class, the knob of the time sweep rate shows for the fastest setting the mark of 0.2 microseconds per major division in horizontal direction on the screen. How many full periods of a 5 MHz periodic signal will be observed in one major horizontal division?

Respuesta :

Answer:

number of full period per major division = 1

Explanation:

given,

20 MHz oscilloscope        

for a 5 MHz signal            

time period of signal          

[tex]T = \dfrac{1}{\mu}[/tex]              

[tex]T = \dfrac{1}{5 \times 10^{6}}[/tex]

T = 0.2 × 10⁻⁶ s                                  

T = 0.2 μs                            

a major division = 0.2 μs                        

number of full period per major division =[tex]\dfrac{0.2}{0.2}[/tex]

number of full period per major division = 1
