by combining signals additively or in product demodulators

Full Title

Demodulation of angle-, modulated oscillations (H03D5/00, H03D9/00, H03D11/00 take precedence) > by detecting phase difference between two signals obtained from input signal (H03D3/28 - H03D3/32 take precedence; ; limiting arrangements H03G11/00) > by combining signals additively or in product demodulators
