Abstract
A programmable range recognizer produces a recognition signal whenever a digital word occurs within a specified closed range of digital words. Such a programmable range recognizer is useful for triggering or data qualification in a logic state analyzer. The range recognizer comprises a random-access memory divided into a plurality of sections, each for decoding a corresponding byte of the digital word, and a combination logic circuit for combining decoded bits to produce a recognition output.
