Abstract
The proposed apparatus and is used for signal generation by multiplexing signals such that there appears no glitches in an output signal. The present apparatus utilizes the knowledge of phase difference between input oscillator signals being multiplexed in order to provide a glitchless output signal. The apparatus comprises a first selection circuit configured to synchronize its response to a first control signal to a next determined event of one of input oscillator signals and convey an input oscillator signal to its output in response to the first control signal. The apparatus comprises a similar selection circuit for each input oscillator signal being multiplexed. Outputs of the selection circuits may be connected to a combining circuit which combines the outputs, thus providing the glitchless output signal.
