1. A pulse generator, comprising:
communication circuitry configured to receive programming instructions sent from one or more electronic programming devices; and
stimulation circuitry configured to generate electrical pulses based on the received programming instructions, wherein:
when viewed in a frequency domain, the electrical pulses have a tonic component and a spread-spectrum component different from the tonic component;
the tonic component and the spread-spectrum component are simultaneously viewable in the frequency domain; and
the spread-spectrum component spans a substantially wider frequency range than the tonic component in the frequency domain, wherein the spread-spectrum component comprises a plurality of non-periodic electrical pulses when viewed in a time domain, and wherein an amount of time between each adjacent pair of the non-periodic electrical pulses is variable.
