Calibrate scope jitter using a transmission line
loop: 09/20/2001 EDN - Design Ideas /
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 fro.
Circuit improves on temperature measurement:
05/02/2002 EDN - Design Ideas / When current
pulses with a stable IHIGH/ILOW ratio modulate a
semiconductor junction, the ensuing voltage
difference (for example, ?VBE 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 covered the relationship
(references 1 to 4) and has numerou....
NCO technique helps ÁC produce clean analog signals:
04/15/99 EDN-Design Ideas / NCO technique
helps C produce clean analog signals. C generates
musical sounds. Continuity buzzer is frugal with
power. Stereo jack adds no-cost power/logic control.
S/H circuit minimizes aperture....
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..
