Information collecting apparatus and information collecting/analyzing system

The information collecting/analyzing system, comprising:

• an information collecting apparatus, including an input unit for inputting digital signals from each part of an object to be measured, for sampling the digital signals, a transfer unit for transferring digital signals form the input unit via a communication interface to a host computer, and a control unit for controlling the input unit and the transfer unit;
• and a host computer, including a signal processing unit for processing digital signals transferred from the information collecting apparatus, a storage device for storing digital signals from the signal processing unit, a display unit for displaying various types of images based on the digital signals processed by the signal processing unit or on the digital signals stored in the storage device, and a control unit for controlling the signal processing unit, storage device and display unit, wherein the transfer unit of the information collecting apparatus transfers digital signals from the input unit on a serial bus in substantially real time to the host computer without initial storage of the digital signals in a high capacity memory prior to processing, and wherein the storage device of the host computer stores logic signals transferred from the information collecting apparatus in substantially real time after processing of the signals.
