1. A method to manage signal data, comprising: acquiring an input datum from signal data generated by a plurality of different sensors, wherein the different sensors further include a plurality of different types of sensors, wherein each different sensor has its own data rate and based on a set of different data rates of the plurality of different sensors, realizing a least common multiplier of the set of different of data rates, wherein the input datum represents sensor data readings contemporaneously collected from the plurality of different types of sensors, wherein each input datum is formed as a multi-bit block of combined sensor data generated by the plurality of different types of sensors, and wherein each input datum is further processed as a single piece of data; advancing a counter each time a new input datum is acquired; if the counter has reached the least common multiplier: saving the new input datum in the memory; and resetting the counter; if the counter has not reached the least common multiplier: identifying a presence or an absence of at least one repetition condition of the new input datum; if the presence of the at least one repetition condition of the new input datum is identified: encoding in a compressed way the new input datum to generate a compressed datum; and saving the compressed datum in a memory; and if the absence of the at least one repetition condition of the new input datum is identified: saving the new input datum in the memory.
