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...
Let h(t) be the impulse response of a causal and stable LTI system with a rational system function. Is the system with impulse response dh(t)/dt guaranteed to be causal and stable?
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 ...
