1. A pulse generator comprising:
a first counter configured to determine a phase of a pulse to be outputted and used for distance measurement to a distance measurement target using an input signal; and
a second counter configured to determine a frequency of the pulse using the input signal,
wherein the second counter generates an output based on the input signal and based on an output of the first counter.
