An analog voltage comparator is configured to convert a modulated signal and output the digital signal. The modulated signal is a 2ASK, 2FSK or 2PSK modulated signal. A sampling decider is configured to sample the digital signal to obtain a sampled digital signal. The sampling decider includes a high-frequency clock sampling circuit and a feature extracting and deciding circuit. The high-frequency clock sampling circuit is configured to sample the digital signal and to sample at least two points for a high level of any pulse of the digital signal. The feature extracting and deciding circuit is configured to extract a feature of the sampled digital signal to obtain an extracted feature of the sampled digital signal, and compare the extracted feature with features of known digital modulated signals to acquire a value represented by the digital signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal demodulation apparatus and method in closed communication system","description":"A signal demodulation apparatus and method for a closed communication system are provided.
