The low-pass filter performs digital differential-integral process on a voltage of an acquired analog signal and a predefined reference voltage to generate differential-integral signals, accumulates a count of the differential-integral signals, and convert the result to an analog signal. By performing differential-integral process accumulating a count of the differential-integral signals, a low-pass filtered signal is obtained in a way that solves the problem of low integrity of circuits in conventional driving systems, reduces the complexity of external circuits for such driving systems and increases their circuit stability."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low pass filter, switch control circuit, driving system, chip and method","description":"A low-pass filter, a switching control circuit, a driving system, a chip and methods are disclosed.
