  • Feedforward amplifiers
    Patent number: 4130807
    Abstract: In a feedforward amplifier the balance of the error cancelling loop can be controlled in amplitude and phase by a variable resistor and a variable capacitor connected to the input to the auxiliary amplifier. This can (a) be used for remotely controlled amplifiers to maximize the effect of phase scatter of third order intermodulation vectors, or (b) in a terminal to introduce deliberate distortion to cancel distortion introduced in line amplifiers.
