Parameter of the rectangular pulses has changed
A spectrum analyzer is connected to a signal that is known to consist of randomly occurring rectangular pulses. The vertical axis of the spectrum analyzer is calibrated in dBm.
The spectrum analyzer has the following display:
A continuous spectrum with magnitude 0 dBm at 0 Hz and zero magnitude at 2 kHz, 4 kHz, 6 kHz, 8 kHz....
a. What is the width of the pulses in milliseconds?
b. If the magnitude of the spectrum increases to +6 dBm at 0 Hz, what is the increase in the voltage of the rectangular pulses?
c. The location of the zeroes in the spectrum suddenly changes to 5 kHz, 10 kHz, 15 kHz.... What parameter of the rectangular pulses has changed and what is its new value?
d. What is the shape of the spectrum displayed by the spectrum analyzer?
