A method for determining the moment of an earliest reception of a signal change and/or a signal edge, in particular for propagation time measurement, in particular for distance measurement and/or synchronisation, in a transmission system, in particular a symbol synchronised and/or digital transmission system, wherein by means of the transmission system at least a first plurality of symbols and/or chips with a first symbol or chip rate is transmitted encoded in at least a first analogue signal from a first to a second object and/or in at least a second analogue signal generated on the basis of the first analogue signal from a first to a second object, wherein a second plurality of samples of a third plurality of the transmitted symbols and/or chips of said at least one first or second analogue signal at the second object is used to detect the earliest reception of the signal change and/ or the signal edge of a symbol or chip different from the preceding symbol or chip, wherein the time at which the earliest of the second plurality of samples or the earliest aggregated group from the second plurality of samples is located, in particular in the signal and/or chip period, is selected as the time of the earliest reception, which exceeds or falls below a value determined from a fourth plurality of samples of the first and/or second analogue signal or leaves a value determined from a fourth plurality of samples of the first and/or second analogue signal, and in particular at which the earliest of the second plurality of samples, in particular in the value range (24a, 24b) of the signal and/or chip period, or the earliest aggregated group from the second plurality of samples, which shows a statistically significant change, is present, the second plurality of samples of the third plurality of transmitted symbols and/ or chips being selected in such a way that their samples are taken at symbols and/or chips transmitted at different times and lie at at least five, in particular at least ten, different, in particular in each case offset by at least two percent of the symbol and/or chip period and/or at least ten, in particular at least 20, percent of the symbol and/or chip period, in particular at least 20 percent of the symbol and/or chip period, wherein the distance in the symbol and/or chip period between the first time points is in particular smaller than the smallest possible sampling interval of the second object of the transmission system, characterised in that samples of a fifth plurality of the transmitted symbols and/ or chips of said at least one first or second analogue signal at the second object are used as the fourth plurality of samples. wherein by means of the transmission system at least a first plurality of symbols and/or chips with a first symbol or chip rate is transmitted encoded in at least a first analogue signal from a first to a second object and/or in at least a second analogue signal generated on the basis of the first analogue signal from a first to a second object, wherein a second plurality of samples of a third plurality of the transmitted symbols and/or chips of said at least one first or second analogue signal at the second object is used to detect the earliest reception of the signal change and/ or the signal edge of a symbol or chip different from the preceding symbol or chip, wherein the time at which the earliest of the second plurality of samples or the earliest aggregated group from the second plurality of samples is located, in particular in the signal and/or chip period, is selected as the time of the earliest reception, which exceeds or falls below a value determined from a fourth plurality of samples of the first and/or second analogue signal or leaves a value determined from a fourth plurality of samples of the first and/or second analogue signal, and in particular at which the earliest of the second plurality of samples, in particular in the value range (24a, 24b) of the signal and/or chip period, or the earliest aggregated group from the second plurality of samples, which shows a statistically significant change, is present, the second plurality of samples of the third plurality of transmitted symbols and/ or chips being selected in such a way that their samples are taken at symbols and/or chips transmitted at different times and lie at at least five, in particular at least ten, different, in particular in each case offset by at least two percent of the symbol and/or chip period and/or at least ten, in particular at least 20, percent of the symbol and/or chip period, in particular at least 20 percent of the symbol and/or chip period, wherein the distance in the symbol and/or chip period between the first time points is in particular smaller than the smallest possible sampling interval of the second object of the transmission system, characterised in that samples of a fifth plurality of the transmitted symbols and/ or chips of said at least one first or second analogue signal at the second object are used as the fourth plurality of samples.
