The Driving Source Design of Differential Susceptibility Detection System Based on ATmega16

摘要: To search the ability of detect metal cracks by differential susceptibility technology, a sawtooth wave driving source system are needed. This is composed generator, control unit, summator and amplifier. And solved problem other can’t output whose frequency voltage adjustable. Compared with source, this one can provide high large current, have higher noise-signal ratio, complete satisfied to demand detection system. Keywords-differential susceptibility; ATmega16;
