In a digital echo eliminator, pseudologarithmic encoding is utilized, which reduces the complexity and the costs, while at the same time improving the function of the echo eliminator. In particular, an improved analogue-to- pseudologarithmic converter, a first and a second method of an improved pseudo-rms-to-dc-converter, an improvedφ, x, function generator and an improved error detector are disclosed. <IMAGE> |
