Novel transistorised lock-in f.m. discriminator
Ernst Bonek, P. Proksch · Electronics Letters · 1970
A novel single-stage transistorised f.m. discriminator is described. It utilises the principle of a lock-in oscillator, and proves to be superior to the ratio detector as far as selectivity, sensitivity, distortions and a.m. rejection are concerned. Also, fewer and simpler components are required.
