widely used to compress the output vectors in BIST (built-in-self- test) [1]–[3]. 32-bit microprocessors like 68020 and 80386 use PSA's in the control part to improve testability. The main disadvantage of using a signature analyzer is the possible occurrence of an aliasing error, which will cause the output response from a faulty
10 Nov 1997 concentrated on combinationalcircuits, this paper investigates signature analysis for a wide range of sequential circuits, where the errors in successive responses are cor- related. It is shown that for almost all faults of these circuits the probability of alias- ing in a signature analyzer with k bits asymptotically
- a summary or tutorial about the signature analyzer or signature analyser, used for fault finding digital or logic electronics circuits. The signature analyzer or signature analyser was an item of test equipment that was used for fault finding digital / logic electronic circuits.

Abstract. The Xylum Clot Signature Analyzer@ (CSA) is an automated, user-friendly, benchtop analyzer that assesses platelet function and coagulation in non- anticoagulated whole blood under physiological flow and temperature conditions. From blood drawn in a single venipuncture, the CSA measures: a) the time for
Purpose. This document is for the purpose of providing a comprehensive explanation of the concept, use and application of Analog Signature Analysis commonly known by the acronym “ASA". The information presented here is intended to be general in nature and not necessarily product or manufacturer specific. However

A signal source generates a sine waveform of voltage at some specific frequency. The voltage is applied to the test point of the circuit, and some resultant
