Abstract:
1. A method of avoiding interfering signals in an electronic system, said method comprising: determining at least one band of interest; identifying at least two band edge frequencies of said at least one band of interest; selecting a first mixing frequency; selecting a second mixing frequency; for a particular harmonic of said first mixing frequency, calculating a harmonic of said second mixing frequency resulting in a spurious signal, from combining said first mixing frequency and said second mixing frequency, on one side of a first band edge frequency of said at least two band edge frequencies and calculating a harmonic of said second mixing frequency resulting in a spurious signal, from combining said first mixing frequency and said second mixing frequency, on said one side of a second band edge frequency of said at least two band edge frequencies; and comparing said first calculated harmonic and said second calculated harmonic.
