VHF/UHF TV Modulator - Simple oscillator that generates a frequency in the
VHF or UHF region. The oscillator is modulated with the video signal and the modulated
carrier wave thus generated is fed into the TV set's aerial input via a cable. Then
all that remains to do is tune the TV to the correct frequency. |

Video Amplifier provides Digital gain control - 08/17/00 EDN-Design
Ideas....Programmable-gain amplifiers, many of them monolithic, are continuously
improving, with lower noise and higher gain-bandwidth products. But for high-end
applications, multichip circuits are still necessary. For example, the amplifier in
Figure 1 originally served as the photomultiplier preamplifier in a Doppler system
intended for eventual operation.... [Design Idea by Stephen Woodward, University of
North Carolina, Chapel Hill, NC] |

Video DVM - Video-DVM is a very cheap DVM that shows how an output as
complex as a videocomposite signal can be generated entirely in software: two I/O pins
and three resistors are all the hardware required. Connected to any TV set it displays
voltages, included max and min peaks, using both giant digits and an analog
bar-display . A serial data output for computer data logging is provided,
too....(added 05/06) |

Video Fader PreServes Synchronization - 07/06/95 EDN-Design Ideas....The
common video effect "fade to black" is usually accomplished by increasing video signal
attenuation to the point where the picture disappears, leaving a black screen. As the
composite signal is attenuated, the signal's sync amplitude becomes too small to
synchronize the picture properly,.... [Design Idea by Frank Cox, Linear Technology

Video multiplexer uses high-speed op amps - 21-Aug-03 Issue of EDN
Video multiplexers route video from several sources to a single channel. Low-end
consumer products use CMOS analog switches and multiplexers, such as the 4066 and
4051. Unfortunately, these devices have a series on-resistance that ranges from
approximately 100Ω to 1 kΩ, a resistance that is not constant with video level and
that appears in series with the signal.... [Design Idea by Bruce Carter, Texas

Video Signal Edge Enhancements - I designed this circuit many years ago,
based on the claims that the technique would improve the quality of standard TV
images. The circuit adds information to the edges of the objects and was reported to
bring out more detail. After building and testing the circuit, I could definitely see
a difference between it and a regular TV display but I don’t think most people would
go to the trouble of installing the circuit for only a marginal improvement. Still, it
is an interesting circuit with which someone might experiment. …. [Designed by David
