A mesh delivery system for controlling electricity supplied to one or more electrical devices from a power source are disclosed. Signals relating to characteristics of the electrical devices are uniformly or non-uniformly sampled at discrete intervals are provided along with associated sampling time indications via the mesh network to a destination controller. The controller applies a compacting algorithm to the received samples and the received associated time indications to generate a paired vector comprising samples and an associated compacted time indication. The paired vector representing the sampled signal in a time domain is transformed into a discrete Fourier spectrum of the signal in the frequency domain where the discrete Fourier spectrum of the signal is in a uniformly sampled in the frequency domain. A filter is applied in the frequency domain to the discrete Fourier spectrum of the signal to generate a filtered discrete spectral representation, and an inverse discrete Fourier transform of the filtered discrete spectral representation is applied to generate a recovered signal in the time domain that is uniformly sampled.
