Abstract: According to one embodiment, an electronic apparatus includes a light source, a detector, an equalizer and a processing circuitry. The light source is configured to emit a pulse having a first output value and a first frequency response. The detector is configured to detect a reflected wave of the pulse and convert the reflected wave to a first electric signal. The reflected wave of the pulse is received after the pulse is reflected by an object. The equalizer is configured to equalize the first electric signal using tap coefficients to generate a second electric signal. The tap coefficients are based on at least either one of the first output value and the first frequency response. The processing circuitry is configured to estimate a distance to the object based on the second electric signal.

Abstract: According to an embodiment, an auto frequency control circuit includes a peak time detector, a first time shifter a zero-crossing time detector, and a second time shifter. The peak time detector detects, from the digital signal, a first time at which the digital signal exhibits one of a maximal value and a minimal value. The first time shifter adds or subtracts a first natural number multiple of the predetermined period to or from the first time. The zero-crossing time detector detects, from the digital signal, a second time at which the digital signal exhibits one of a positive zero-crossing and a negative zero-crossing. The second time shifter adds or subtracts the first natural number multiple of the predetermined period to or from the second time.

Abstract: A resonance frequency detector has an adder that adds a correction term to an oscillation frequency of an output signal of an oscillator, and detects a predetermined resonance frequency of a resonance element. The correction term is generated based on a phase error in a phase locked loop and a degree of change in phase at the resonance frequency, and the phase locked loop generates a control signal based on the phase error between an output signal of the resonance element that resonates at the resonance frequency and the output signal of the oscillator that varies the oscillation frequency according to the control signal.
