The period of this signal is about ms (milliseconds). Use this picture for 2 additional questions below. 0.5 0.2 0.2 10. . 0.1 10. . 0.1 OFF Vidiv ms/div oscilloscope The oscilloscope range selector determines the scale on the screen. That means number of Volts per line for amplitude vertical (V/div) and the number of milliseconds per line for time horizontally (ms/div).

How does the oscilloscope graph show the transient response to voltage/current in a RL circuit?

# The figure above represents the spectrum of a pulse train, Fo= 2KHz 1- What is the frequency of the fourth harmonic? 2-What is the power of the Second harmonic? 3- When does the first null occur? 4- Calculate the duty cycle of this signal. 5- What does the space between the pulses equal 1? Reference level = 20 dBm Centre Frequency = 40KHz Span 80KHz/ division
