Circuit test method |
May 11, 1993 |
| The present invention relates to a method of testing of digital and analog circuits. If a fault is detected, after stimuli are applied and test measurements are made at some circuit nodes, steps are taken to locate faulty circuit components. At least one further node is selected for |

Analog to digital converter |
April 21, 1992 |
| A continuous ADC for generating a digital representation, corresponding to a given quantized voltage level, of an analog input signal and for updating the digital representation at times when the approximate amplitude of the analog signal changes from one quantized level to another. |

General network modeling and synthesis |
September 10, 1991 |
| A method and apparatus for modeling and synthesizing the response of a network to selected input signals where the input signals may be multi-channel in analog or digital form, and where the network's response may be linear or non-linear and depend on the present input signals as wel |

Analogue-to-digital converter |
May 28, 1991 |
| A multiple ramp analogue-to-digital converter comprises an integrator connected to receive and integrate an analogue input signal to be converted, and an opposing coarse reference signal. Instead of these signals being applied to the integrator sequentially, as is conventional, they |
