The evaluation of the recorded impulse oscillogram utilises a digital calculator. High accuracy demands are fulfilled by means of a two-tube arrangement, by which the difference between the reflected impulse at the 'live' terminal and that at the measuring object is recorded.The possibility of ...
An echo canceller, using an Adaptive Finite Input Response Filter (AFIR), uses a processing device with a plurality of interconnected cells. These cells, connected in a systolic arrangement, determines the function of three variables m, n, and p, in the equation p+m n, where m and n are...
