Converter for converting a downward modulated signal of high frequency in a low frequency signal.Converter for converting a signal ascending low frequency signal in a high frequency modulated, equipment to reconstruct a signal of low frequency.And to generate a signal of high frequency of a composite modulated signal, and processes to convert descendentemente a high frequency radio signal modulated into a signal of low frequency.To convert upward a signal of low frequency for a signal of high frequency, to reconstruct a signal of low frequency of a signal composite.And to generate a signal of high frequency signal of a composite ".A downward converter converts a signal of high frequ00b3u00eancia amplitude modulated signal and a low frequ00b3u00eancia or the base.A first mixer (30, 32) mixes the signal of high frequ00b3u00eancia in a composite signal having a phase component and a quadrature component.A filter pass band complex (34) limits the bandwidth of the signal into a composite signal of bandwidth limited with a component in phase and quadrature component.A second mixer (36, 38) mixes the signal bandwidth limited in an intermediate signal with a phase component and a quadrature component.An adder (40) adds a component of the intermediate signal to the other. An upward converter similar performs the reverse process.
