Calibrate scope jitter using a transmission line loop - 20-Sep-01
Issue of EDN Digital-clock-period jitter is the variation in the
period of a clock cycle compared with a nominal (average of many cycles]
clock period. To accurately measure period jitter using an oscilloscope, you
must subtract the oscilloscope jitter from the measured jitter..... [Design
Idea by David Cuthbert, Micron Technology, Boise, ID] |

Circuit improves on temperature measurement - 2-May-02 Issue of
EDN When current pulses with a stable IHIGH/ILOW ratio modulate a
semiconductor junction, the ensuing voltage difference (for example, ΔVBE
for a bipolar transistor] is a linear function of the absolute (Kelvin]
temperature, T. You can use this truism to make accurate temperature
measurements. Technical literature has thoroughly.... [Design Idea by
Alexander Bell, Infosoft International Inc, Rego Park, NY] |

NCO technique helps µC
produce clean analog signals - 04/15/99 Issue of EDN A recent Design
Idea described a method for producing an analog voltage from one digital output of a
µC ("Generate an analog signal with a µC," EDN,Oct 22, 1998, pg 108]. The method
involves generating a PWM output with a controlled duty cycle...[Design Idea by Steve

RF Transmitter uses AMI encoding - 11/24/99 EDN-Design Ideas....Although
alternate-mark-inversion (AMI]encoding is well-suited for direct-conversion FM
transmission, designers often overlook the technique. AMI, a three-phase,
synchronous-encoding technique, uses bipolar pulses to represent logic ones and no
signal to.... EDN is migrating links. This link is not verified. Search the
