Abstract
In this paper an alternative technique for differential gain and phase testing of video ADCs based on the use of joint time-frequency analysis is presented. This technique can lead to a significant improvement in ADC testing time and in the amount of information provided by these specific tests.

Abstract
This paper investigates the use of mixed-signal test support ICs to extend a digital, board level test infrastructure to the analog section of a mixed-signal board. The architecture of a prototype test support IC is described and its application to the test of an infrared emitter-receiver board is discussed.

Abstract
A new wearable data capture system for gait analysis is being developed. It consists of a pantyhose with embedded conductive yarns interconnecting customized sensing electronic devices that capture inertial and electromyographic signals and sends aggregated information to a personal computer through a wireless link. The use of conductive yarns to build the myoelectric electrodes and the interconnections of the wired sensors network, as well as the topology and functionality of the sensor modules are presented.

Abstract
The increasing complexity of mixed-signal boards makes an integrated analogue/digital testability approach an attractive proposition. This paper investigates one such approach based on the use of mixed-signal test support ICs together with standard board level test infrastructures. The architecture of a test support IC and preliminary experimental results are also presented.

Abstract
The paper discusses the need of a test infrastructure to support the testing of mixed-signal electronic systems, and discusses a general architecture for test support ICs that can be used to build it. An implementation of a subset of this architecture is described together with its application in a practical example.
