  • Noise generator having variable bandwidth and center frequency
    Patent number: 4475090
    Abstract: A noise source is coupled through a first bandpass filter to a first mixer to which a first local oscillator signal is applied. The output of the first mixer is coupled through a second bandpass filter to a second mixer to which a second local oscillator signal is applied. At the output of the second mixer is obtained a noise signal having a bandwidth that can be varied by varying the frequency of the first local oscillator, and having a center frequency that can be varied by varying the frequency of the second local oscillator.
