ABSTRACT:
Signal comparison arrangement for comparing a first and a second analog signal with each other. For each of these signals the number of zero-crossings occurring within each measuring interval of a sequence of N consecutive measuring intervals T(1), T(2), . . . T(N) is counted. The N numbers x(1), x(2), . . . x(N) which represent the numbers of zero-crossings of the first analog signal in the consecutive measuring intervals T(1), T(2), . . . T(N) and the N numbers y(1), y(2), . . . y(N) which represent these numbers of zero-crossings of the second analog signal in the said measuring intervals, are applied to a programmable computer which determines the value of a statistical quantity by means of these 2N numbers and compares this value with a threshold value. This statistical quantity may be formed by the directional coefficient of a straight line which is closest to either the N numbers x(n), or the N numbers y(n), but may alternatively be formed by the correlation coefficient.
