Title: Determining variation of spectral lines of signal patterns
IPC: G10L19/02
Filed: 1987-06-30
Abstract: Consecutive signal components are digitally captured and the signals are subjected to a fast Fourier transform in which the numbers of measurement values of each signal component capturing the fundamental period are arranged in a repetitive sequence until a number suitable for the fast Fourier transform is reached or even exceeded. The signal series thus composed is subjected to the fast Fourier transform. The analog-digital conversion of the signal which is to be analysed is carried out with a sampling frequency which is higher than would be necessary according to the requirement of the sampling theorem for the highest frequency to be analysed. The invention can be used in technical diagnosis, in speech analysis and in certain medical applications. <IMAGE>

Abstract: In a wireless communication system provided with a WAP (wireless application protocol) server which can convert different data and protocols into available data and protocols between the wireless communication system and an Internet server, a method of designating a WAP server address and a wireless communication system are disclosed. The method includes the steps of deciding via a switching system whether the registered position of the wireless communication terminal which requests the registration is changed to another registered position after confirming via the switching system whether the wireless communication terminal is eligible when a wireless communication terminal requests a registration; and answering the registration request and simultaneously transferring the address information of a corresponding WAP server via the switching system to the wireless communication terminal when the registered position of the wireless communication terminal is not changed in the above step, and answering the registration request and simultaneously transferring the address information of a corresponding WAP server via the switching system to the wireless communication terminal when the registered position of the wireless communication terminal is changed in the above step. Consequently, there is an advantage in which, according to the movement of the wireless communication terminal, a corresponding WAP server address is automatically transferred to the wireless communication terminal. The wireless communication system is provided with a WAP server which can convert different data and protocols into available data and protocols between the wireless communication system and an Internet server.
