Частотная модуляция (ЧМ) или frequency modulation (FM) является разновидностью угловой модуляции.

За основу взята схема модулятора отсюда: http://everycircuit.com/circuit/5217896938602496

Частотный дискриминатор, расположенный сверху, выполнен по классической двухконтурной схеме. Нижняя схема дискриминатора построена на квадратурном детекторе (разновидность балансного модулятора).
Третий возможный вариант построения частотного дискриминатора основан на использовании ГУН с ФАПЧ (PLL).

Frequency modulation (FM) or frequency modulation (FM) is a kind of frequency modulation. For the basis of the modulator circuit here: http://everycircuit.com/circuit/5217896938602496 Frequency discriminator disposed on, made by the classical two-loop. Lower discriminator circuit is built on a quadrature detector (a kind of balanced modulator). A third option of constructing a frequency discriminator based on the use of a VCO with PLL (PLL).
