Abstract: An electrical circuit can have a local oscillator, a first mixer, a second mixer, and a delay element. The first mixer mixes an input signal with a local oscillator signal. The second mixer mixes the input signal with a delayed local oscillator signal, delayed by the delay element. The output signals from the first mixers are combined to form an output signal of the electrical circuit.
