Suhteavastil on Fosteri–Seeley suhtedetektori ees eelis, et ei reageeri amplituudmodulatsiooni signaalidele, säästes seega potentsiaalselt piiraja etappi, ning sellel on laiem ribalaius, kuid rohkem moonutusi kui Fosteri–Seeley suhtedetektoril.
The ratio detector has the advantage over the Foster–Seeley discriminator that it does not respond to amplitude modulation signals, thus potentially saving a limiter stage; however, the output is only 50 % of the output of a discriminator for the same input signal, and has wider bandwidth, but more distortion than the Foster–Seeley discriminator.
