Understanding Intermodulation Noise and Intermodulation Products

WebThird-order intermodulation distortion (IM3) for a frequency fil-ter occurs when system nonlinearities allow out-of-band signal components (tones) spaced from an in-band frequency ωo by ∆ω and 2∆ω, respectively, to generate an in-band component SIM3 back at ωo [5]. This phenomenon can be illustrated quantitatively by WebIntermodulation distortion. ... To be able to select five channels without any third order intermodulation products being produced, it is necessary to have 12 regularly spaced (e.g., 25 kHz spaced) channels available. Channels 1, 2, 5, 10 and 12 will not give rise to the …
