This paper deals with the principle of compressing the geopnone signal to one bit recording by means of the pseudo-random code theory. For the first time it gives a mathematical model of amplitude recovery. By way of a simple example, the paper describes the process of compressing the geophone signal to one bit recording and the recovery of the amplitude. Some preliminary observations are made on the following problems such as the accuracy of amplitude recovery of one bit recording and the difference between one bit recording and sign bit recording and so on. The possible applications of this technique are suggested as well.
