Come tradurreste "stepped" / "steppiness"?

Qui "stepped":

"It is this shifting sampling position on each chip, coupled with filtering the input using a matched filter (or approximation thereto, as explained below), and choosing a single sample for input to the correlator that provides a key benefit of the invention. Without the differing sampling position, in choosing the closest sample to the desired ideal position, the SSU would always choose a sample with a constant positional error. This would lead to a correlation function having a stepped characteristic, which is not ideally suited for tracking a correlation peak."

"Before this invention, it was understood by those skilled in the art that having a sample rate equal to the chip rate did not provide a practical discriminator function - the function would, with no matched filter being present, resemble a flat topped pulse as shown in Figure 3a which is unable to provide tracking feedback in a tracking loop. Having a fixed integer multiple of samples per chip improves on this, but results in a discriminator function that is a stepped amplitude pulse, as shown in 3b, with the number of steps equal to the number of samples per pulse (e.g. 4 samples per chip in the case illustrated in Figure 3b)."


Qui "steppiness" (compare tra virgolette):

"Since in that case the delay times of the available samples relative to the start of each chip are the same relative to each chip start, and since the ideal sampling times also have the equal delays relative to the start of successive chips, each operation of the sample selector (63) selects a sample whose delay relative to the start of the corresponding chip is the same. The error (i.e. difference) between the ideal sample times and the selected sample times is therefore the same for each chip, and may be non-zero. The average value of the error (that is, the bias) may therefore be non-zero. The consequence is that samples used to form the correlation then correspond to a time delay different from the ideal one. This creates the "steppiness" in correlator response described previously, which is an undesirable error."
