The control system of high precision micro-displacement platform has been designed according to the high precision, high speed and high stability requirements. A hardware platform has been established with 24-bit A/D chip, D/A chip, and TMS320C6713 DSP chip. An improved PID control algorithm was put forward combining set-point weighting control algorithm, resisting saturation of integral with tracking...
Based on the design concept of software radio, the digital intermediate frequency module was constructed in the wireless broadband receiver in order to enable the functionality of frequency mixing, decimating, filtering and modulating. Digital intermediate frequency module mainly consists of CIC decimation filter, FIR filter, CIC interpolating filter and NCO. Arithmetic study has been done to all...
