ABSTRACT:
A method of random sampling a signal includes determining a bounded sample timing interval, and acquiring a sample of the signal at random sample times within the bounded sample timing interval. Sample acquisition is repeated until the signal to noise ratio of an estimated spectrum of the signal, produced from the acquired samples, achieves a target signal to noise ratio.
