Discussion
Assertion: aliasing can be recognised by changing the sweep speed. Reason: an aliased frequency depends on the sampling rate as well as on the signal.
Answer: A
Changing the sweep speed changes the sample rate, and since the alias frequency is the difference between the signal and a multiple of the sample rate, the displayed frequency shifts. A genuine signal would keep its frequency and merely occupy a different number of divisions.
