The present disclosure provides techniques and apparatus for decoding of a biphase signal in a wireline modem. An example technique involves receiving 902 a biphase modulated signal from a surface ac

A motor controller with a data bit expansion mechanism is provided. The motor controller sets a plurality of pieces of target waveform characteristic data that are used respectively within a plurality of magnetic pole position time intervals to output a motor control output instruction. The motor controller, according to each of the plurality of pieces of target waveform characteristic data, generates a plurality of pieces of sub-target waveform characteristic data in a bit number expansion instruction. The plurality of pieces of sub-target waveform characteristic data are used respectively within a plurality of bit expansion time intervals. The bit number of each of the plurality of pieces of sub-target waveform characteristic data is smaller than an upper limit bit number. The motor controller generates a plurality of bit-expansion waveforms according to the bit number expansion instruction for controlling a motor.

The application discloses an FM0 decoding method and device with anti-interference capability, and comprises the following steps: S1, four one-bit-width FIFOs, fifo0, fifo1, fifo2 and fifo3, input signals are sampled by a clock and stored in the FIFOs, and two FM0 encoding bit time sampling data are stored in the FIFOs; S2, four accumulators record the accumulated values of the sampling values in the corresponding FIFOs; S3, the four accumulated values are respectively judged as high or low F0, F1, F2 and F3; S4, after being converted into absolute values, the accumulators are summed to obtain a total value; S5, the change of the total value is used to find a peak value, and the peak value is used to correct a sampling time; and S6, whether the high and low values and the total value are greater than a threshold value is used to judge whether the FM0 encoding is valid, and the FM0 output data is valid, and the application relates to the technical field of communication. The application solves the problem that many high-frequency interferences often occur in a real communication system, and the interferences can cause communication failure of a decoding method relying on a jump time.
