Abstract
In a receiver for FSK modulated signals, an input signal is applied to a converter ( ) which mixes the input signal with a local oscillator frequency. The frequency of the local oscillator is unrelated to the frequencies of the FSK signal, resulting in a larger degree of freedom for choosing the local oscillator frequency. This oscillator frequency can e.g. be chosen to be one fourth of the sample frequency the input signal is sampled with.
