Latest Patents

Among his latest innovations is an amplitude modulation detector that utilizes peak detection. This invention includes a Customer Premise Equipment (CPE) Alert Signal detection apparatus and a caller information detection apparatus. Both systems employ peak detection methods for CAS and caller information detection. The CAS detection apparatus comprises a mixing unit, an amplitude modulation detection unit, and a frequency discriminating unit. The mixing unit is responsible for mixing two or more frequency components of the input signal to generate an amplitude modulated signal that includes both a carrier and an envelope. The amplitude modulation detection unit measures the envelope, while the frequency discriminating unit determines whether the frequency of the envelope falls within a predetermined range to identify the presence of the CAS. This innovative approach allows for the detection of the CAS through a single path by mixing a dual-tone CAS signal, ensuring accurate detection by discriminating the frequency of the envelope. Furthermore, the amplitude detection unit can be digitally implemented, enabling the CAS detection apparatus to be integrated into a single chip without the need for external components. This amplitude modulation detection unit can be applied across various systems that utilize amplitude modulation, including the CAS detection apparatus.
