This paper contains things around noise band, the udp measurement, network, and clock skew measurement. Many things like frequency, measurement, quantisation noise, and synchronisation are explained in this paper.
Inside this paper we can read info related to quantisation, interval, the quantisation noise, and duration. Below are excerpted from this paper:
The Tor anonymisation network allows services, such as web servers, to be operated under a pseudonym. In previous work Murdoch described a novel attack to reveal such hidden services by correlating clock skew changes with times of increased load, and hence temperature. Clock skew measurement suﬀers from two main sources of noise: network jitter and timestamp quantisation error. Depending on the target’s clock frequency the quantisation noise can be orders of magnitude larger than the noise caused by typical network jitter.
Furthermore, the paper presents discussion such as skew measurement, noise, noise distributions, and measurements.
