Monitor Test Program 2008-07-10 12:21:19 The Monitor
Test program is a Windows application which comes in the help of electronics technicians for adjusting computer monitors and for general users for testing the quality of their monitors.It displays different patterns on the screen and it also allows to change the resolution from 640x480 to 1600x1200. These patterns are useful for checking or adjusting the convergency, focus, brightness, Read more:Program
Triple Video Buffer with Filter TSH173 2008-06-28 12:26:21 This Triple
Video Buffer

Video Buffer and Filter with SAG Correction Based on The TSH120 2008-06-28 12:01:41 This evaluation board Video Buffer
and Filter
circuit is based on the TSH120 video buffer. The TSH120 includes a voltage feedback amplifier with an internal gain of 6 dB, rail-to-rail output, internal input biasing and SAG correction. A power-down function provides a sleep mode with ultra low power consumption.FeaturesVery low consumption in active and standby modeInternal reconstruction filterInt
Video Modulator Circuit TDA6800(T) 2008-06-22 10:22:15 The TDA6800 is a modulator circuit for modulation of video signals on a VHF/UHF carrier. The circuit requires a 5 V power supply and few external components for the negative modulation mode. For positive modulation an external clamp circuit is required. This circuit can be used as a general purpose modulator without additional external components.Features· Balanced modulator· Symmetrical oscilla Read more:Circuit
The Difference Between a RF Modulator and Video Switcher 2008-06-22 09:46:05 RF modulators make it possible to connect devices to televisions where it would otherwise be impossible to. Video switchers make it possible to connect more than one device to the same input without the need for changing out the wires every time you want to switch equipment.RF ModulatorsRF modulators are useful devices for people who own televisions with RF/coaxial-only inputs because without the Read more:Switcher
AM Video Modulator 2008-06-22 09:38:41 The first section of the video modulator performs a video level clamping function. The high input impedance Darlington amplifier and the small series coupling capacitor combine to achieve an excellent low-frequency response and a clamping function with very rapid response time. A three terminal voltage regulator sets the clamping level to 8 volts.The clamped video is then level shifted through a z
Video Amplifier with Sync Stripper and DC Restore EL8102 2008-06-17 00:45:08 The circuit transmits 200MHz (-3dB bandwidth) video signals while stripping off the sync pulse and performing DC restoration. It is configured for a typical video cable driver application driving a double-terminated 75Ω load, where the EL8102 (IC3) is configured for a gain of +2 to ensure unity gain throughout.Sync StrippingIn component video systems it is frequently necessary to remove the sync Read more:Amplifier

Connecting your Computer to a Television 2008-06-15 09:27:34 It is a nasty surprise when you switch your monitor on and nothing appears on screen after a patient wait. Even though the resolution is much low, a television may help you to conduct basic procedures (copying your files for example) in such an emergency. You may think that this is only possible through expensive VGA cards but it's not true. A simple circuit can combine the VGA synchronization sig Read more:Computer

Video Signal Amplifier 2008-10-25 07:46:41 This electronic circuit is a video signal amplifier that offers a broad band amplifier with a bandwidth of 5 MHz which will take the video signals from your VCR and will amplify them sufficiently to drive up to 3 monitors, TV sets (provided that they can accept direct video signals), or other VCR�s for recording from one video to up to three others.
The video signal amplifier will also make p Read more:Amplifier
PIC16F84 Video Generator 2008-10-08 22:36:31 Here's the project was to construct a Composite Video Pattern Generator
, which can be used as a teaching tool in the video field as well as a laboratory instrument, useful for repairing and adjusting television receptors.
This video generator instrument is in no way intended to be a commercial set, because I cannot guarantee all the specifications that a professional tool must have. However, the
