<p>This circuit comprises an analog/digital converter (126), a random- access memory (128) for acquiring samples, a read-only memory (152) containing the coefficients of the transform, a counter (132) addressing both memories, a multiplier (160) connected to both memories, an accumulator (170) and a sequencer for controlling the whole. Application to the construction of devices for non-destructive testing using eddy currents. <IMAGE></p> |
