Filter circuitry is constituted by transversal filters which are connected in parallel to each other. The transversal filters change amplitude and a phase of an input digital signal X.sub.in[n.Math.T.sub.s] and output different digital signals X.sub.1[n.Math.T.sub.s], X.sub.2[n.Math.T.sub.s], and X.sub.3[n.Math.T.sub.s] as respective resulting digital signals whose amplitude and phase have been changed. A phase frequency computer computes a phase θ.sub.X[n.Math.T.sub.s] and a frequency f.sub.X[n.Math.T.sub.s] of the input digital signal X.sub.in[n.Math.T.sub.s] by performing phase computation and frequency computation using the digital signals X.sub.1[n.Math.T.sub.s], X.sub.2[n.Math.T.sub.s], and X.sub.3[n.Math.T.sub.s] output by the transversal filters.

A confined data communication system includes a reference generation circuit operable to produce one or more analog reference signals, an analog to digital converter circuit operable to process an analog signal to produce a digital representative signal, a digital filtering circuit operable to filter the digital representative signal to produce an affect value, a data processing module operable to interpret the affect value to produce processed output data, and a processing module operable to set frequency and waveform for each of the one or more analog reference signals, set digital filtering parameters for the digital filtering circuit, set a sampling rate for the analog to digital converter circuit, and set data interpretation parameters for the data processing module.

A method, an apparatus and a device for simultaneously sampling multiples signals and a medium are provided. The method includes: modulating multiple target input signals with CDM, to obtain a single target analog signal; performing ΔΣ modulation on the single target analog signal to obtain a target digital bit stream; demodulating the target digital bit stream to obtain a target demodulated bit stream; and filtering the target demodulated bit stream to obtain multiple target output signals. With the method, the hardware overhead for simultaneous sampling of multiple-channel signals is reduced while ensuring accuracy. Accordingly, the apparatus and the device, and the medium have the above beneficial effects.

Systems and methods for producing a linear-phase digital FIR filter from two sub-filters for an audio signal. In one method, the sub-filters are provided as sub-sets having numbers of coefficients, a lower cutoff frequency of the particular sub-filter being greater than the sampling frequency of the audio signal divided by the number. The sub-sets are linearly convoluted with one another so as to form a total set having a number of coefficients greater than the numbers, and the total set is symmetrically reduced to a number less than the number, so as to form a reduced total set of the filter. A linear-phase digital FIR filter for an audio signal is created by the method.

A method is provided that includes performing, by a processor in response to a vector sort instruction, sorting of values stored in lanes of the vector to generate a sorted vector, wherein the values in a first portion of the lanes are sorted in a first order indicated by the vector sort instruction and the values in a second portion of the lanes are sorted in a second order indicated by the vector sort instruction; and storing the sorted vector in a storage location.

An interleaved cascaded integrator-comb (“CIC”) filter receives an interleaved sensor output signal, including a plurality of digitized sensor signals at an input clock rate. An integrator of the interleaved CIC filter processes the interleaved signal to output an integrated interleaved signal. A downsampler of the interleaved CIC filter buffers portions of the integrated interleaved corresponding to a decimation rate for the interleaved signal. The portions of the signals are provided to a comb filter, which outputs a decimated interleaved signal.

A filter control method controls a filter that controls frequency characteristics of a sound signal over a plurality of bands. The filter control method is implemented by a computer. The filter control method includes accepting a specifying operation from a user to specify a latency of the filter as a desired latency of the filter, accepting a setting operation from the user to set desired values of two or more parameters, which include phase characteristics and gain, for a respective band among the plurality of bands within a limit range determined based on the desired latency, and generating coefficients for the filter based on the desired values of the two or more parameters for the respective band.
