Feedback technique improves oscillator phase noise

Article Abstract:

The feedback technique significantly reduces oscillator phase noise by using internally generated noise to provide cancellation of close-in oscillator noise up to 1-MHz bandwith. When used to oscillators operating from the VHF range up to millimeter-wave frequencies, a noise reduction of over 15-dB is achieved at microwave frequencies. This feedback method can be incorporated in the oscillator's biasing circuit and requires only an additional wideband DC-biasing circuit in order to apply noise feedback.

Compute CTB in hybrid fiber/coax systems

Article Abstract:

Cambridge, MA-based MathSoft Inc's MathCAD mathematical modelling program has been used to predict the composite-triple-beat and composite-second- order distortion levels for analog and digital signal planning in cable television systems. The software calculates the number of triple beats of type A+B-C in a particular channel and generates a plot of beat count as a function of frequency.
