Abstract
A signal processing system is provided and includes: a measurement apparatus that measures current and voltage which are supplied to a plurality of electric devices; and a processing apparatus that is connected to the measurement apparatus that estimates operation conditions of the respective electric devices. The measurement apparatus includes a detection unit that detects analog waveform data, a conversion unit that samples the analog waveform data and converts the sampled analog waveform data into digital waveform data, and a transmission unit that transmits the digital waveform data to the processing apparatus. The processing apparatus includes a reception unit that receives the digital waveform data, a storage unit that stores the digital waveform data, a separation unit that separates the stored digital waveform data into pieces, and an operation estimation unit that analyzes the pieces of digital waveform data and estimates the operation conditions.
