Adding
synchronous rectification is
made easier with ferrite
beads:
06/14/99 Electronic Design -
Ideas for Design / To
increase efficiency in
portable applications, many
designers have turned to
synchronous rectification
for low-voltage switching
power converters. This is
usually implemented using a
power. . . |

Stable Triggering of
Oscilloscope Video Waveform
Displays -- Have you been
frustrated by video
waveforms which are
difficult to display on your
oscilloscope? Do you have to
readjust the trigger level
every Time the scene
changes? This article
describes a simple circuit
that will allow a triggered
sweep oscilloscope to
provide the most important
capability of a video
waveform monitor, a stable
display of the video
waveform.

One Chip Sync
Mixer:
This simple circuit combines
separate sync signals
to1-negative composite sync
signal. This circuit is
originally designed to hook
up a CGA to display which
needs composite sync signal.
Can be adapted for other
uses. |

Using the
LM1881 Chip:
This is quite a nice chip,
and has myriad uses. Since
most game systems output the
composite sync information
along with the NTSC video
output, and since most RGB
monitors will not accept
this extraneous info along
with the sync, we need to
remove the video signal. The
LM1881 does an admirable job
of this. |
