1. An electronic device of a sensor comprising circuitry configured to generate a coded modulation signal for modulating illumination light transmitted by a time of flight camera of the sensor, wherein
the coded modulation signal comprises a high frequency generated by a modulation clock and a low frequency corresponding to a frequency of the envelope of the coded modulation signal, and
the coded modulation signal is generated by on/off keying of the modulation clock.
