Abstract:

This patent describes an A.C. coupled, low-pass translating filter in which quadrature phases of an input signal spectrum are, in three successive balanced modulator stages driven by quadrature phases of externally generated carrier signals, alternately modulated-up and demodulated-down, and the sum of the remaining spectra is, in a final stage, demodulated below the cutoff frequency. Each stage terminates with a low-pass filter in which odd harmonics of the carrier frequencies and double frequencies generated in the second and final stages are eliminated. Author
