Abstract
The occurrence of spurs when analyzing signals is reduced. A first signal is mixed with a local oscillator signal to produce an intermediate signal. When a spur is predicted to occur when high side mixing is performed, low side mixing is performed. When a spur is predicted to occur when low side mixing is performed, high side mixing is performed.
