Classification: CPC G | IPC G

Claim 8:
9. A time-of-flight converter comprising:
a transmitter frontend with at least one output terminal connected to at least one transducer, the transmitter frontend configured to generate an output signal to drive the at least one transducer to transmit a signal train through a medium, wherein the signal train comprises a sequence of waves of a first group and of a second group, and wherein the first and second groups are shifted by an inserted predetermined phase shift in a time domain such that the first group of waves is transmitted earlier in time than the second group of waves;
a timing register block with at least one input terminal configured to receive an input signal as a function of time; and
a processor configured to:
detect a phase shift in the input signal;
assign wave periods of the input signal to respective wave periods of the first group using the detected phase shift as a reference; and
determine a sequence of time-of-flight signals from the sequence of waves of the first group and the assigned wave periods of the received input signal, respectively.
