The following shows the configuration for a 3-bit Johnson counter.
If the frequency of the clock signal is 18 MHz, then the frequency of the signal seen at the output of FF C would be ____ MHz.
Round your answer to one decimal place.
Hint: The formula for this has not been covered in the lecture notes! Draw an example clock waveform and draw the waveform that you would see at output C. Figure out what the relationship is between the two.
