A pitch search method and device for digitally encoding a wideband signal, in particular but not exclusively a speech signal, in view of transmitting, or storing, and synthesizing this wideband sound signal. Data associated with respective dates is retrieved and displayed, each set of data being displayed in a display screen that is displayed smaller than that for preceding data in the series. End tapers can bias adjacent pairs in opposed directions responsive to applied differential pressure. Another adaptation provides a microelectronic component test system including a microelectronic component including a plurality of terminals.
