In order to overcome the disadvantages that simple genetic algorithm had in low-dimensional and multimodal function optimization, an improved algorithm was proposed. The new algorithm divided the search interval into different areas by method of orthogonal decomposition, produced initial populations that had different individual distribution density by using interval algorithm, and gave each individual...
In order to sample two channels mixing frequency signals in high speed and process them synchronously in the system, a dual-channel, high-speed digital lock-in amplifier (LIA) that uses orthogonal digital demodulation is proposed. The instrument, based on a digital signal processor (DSP) and its associated hardware, is implemented. The system adopts a method of high speed bi-directional parallel communication...
