In a distance measurement apparatus, a light emitter emits pulse-like light. A light receiver receives reflected light of the emitted light and converts the received light to an electrical signal. An AD converter converts the electrical signal to a digital value at a predetermined sampling rate to generate a conversion data series. An interpolation processor upsamples the outputted conversion data series by inserting interpolation data therein to generate an up-data series. A distance calculator calculates a distance to an object that reflects light using a signal waveform indicated by the up-data series. The interpolation processor inserts the interpolation data having an interpolation value between pieces of data belonging to the conversion data series, and smooths the data series in which the interpolation data is inserted using a low-pass filter that has characteristics in which waveform distortion caused by ringing does not occur.

A phase shifter for altering the phase of a radio frequency signal is disclosed herein. A Lange coupler is used having reflective ports that are coupled to artificial transmission lines. The artificial transmission lines provide a reflection transmission path, the length of which can be determined by digital control lines. Transistors placed along the length of the central trace provide independent paths to ground that serve to shorten the electrical length of the ATL. Accordingly, by selectively turning the transistors on/off, the electrical length of the ATL can be selected and thus the amount of phase delay introduced by the phase shifter.

Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a millimeter wave (mmW) radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the signal at the mmW radio frequency. Repeaters may include analog and digital components for downconverting on the received signal to reduce a frequency of the signal from the mmW frequency to an intermediate frequency (IF) or baseband frequency, and then filtering the downconverted signal to reduce interference. The filtering may include digital filtering or a combination of analog and digital filtering, in which a set of filter coefficients for the digital filtering is selected based on beamforming parameters used to receive the signal, retransmit the signal, or both. The repeater may then upconvert the filtered signal back to the mmW frequency for the retransmission of the signal.

A process for processing a digital signal comprises constructing a fractional order control system that models a desired frequency response by assembling filter components from a filter component library. The filter components are defined by Laplace functions that include a non-integer control order having a variable fractional scaling exponent. Then, the fractional order control system is adjusted by applying an altitude exponent to the fractional order control system, and the altitude exponent changes a magnitude of the frequency response without changing a width of a transition band of the frequency response. An input signal in the digital frequency domain is received and processed based upon the fractional order control system to generate a digital output that is conveyed.
