            Abstract : 
An operator treatment of modulated carriers in linear, time-invariant, nongenerative networks is given. The modulation is split up into an in-phase and a quadrature component. An operator (jω0+ λ) is introduced, ω0/2π being the carrier frequency and λ the operator d/dt acting on the modulation only.
