Selective network and then impressing the output voltages upon the grid of a detector. This process is treated analytically and formulas are given which permit the calculation of low-frequency detection products in terms of the transmission characteristic of the distorting network and the maximum frequency shift during modulation. 

Measured detection products produced in such a system are compared with values calculated by means of the formulas which are given, and the results are shown to be in substantial agreement over the region in which certain simplifying assumptions are justified.
