According to the invention there is provided a method of producing an output signal including the steps of: providing an electronic oscillator having a switching arrangement allowing the oscillator to be switched between at least a first configuration having an associated first oscillator frequency and period, and a second configuration having an associated second oscillator frequency and period, and a control arrangement for controlling the switching arrangement; dithering the oscillator between at least the first configuration and the second configuration to produce the output signal, having an intermediate frequency and period, in which the dithering is performed by switching from the first configuration to the second configuration for a pre-determined subset of each output signal period over successive cycles of the output signal frequency. |
