Sync Signal Separator

ElectroSchematics.com — Sat, 03 Jul 2010 17:14:51 +0000

This simple sync signal separator circuit separates the composite sync signal into 2 separate horizontal and vertical sync signals. The composite signal can be directly used to drive the monitor’s horizontal sync input. That is why the composite signal line is connected directly to the H-sync line. To get the vertical sync signal, the double [...]

S-Video to RCA Cable

ElectroSchematics.com — Sun, 31 Jan 2010 01:54:36 +0000

The S Video to RCA cable is sometime hard to find and the adapter is almost every time too short. I’ve searched at my local store and haven’t found any. So I’ve decided to search on google and found some useful sites so is easy to make on your own SVideo to RCA adapter with [...]

CGA / SCART adapter

ElectroSchematics.com — Sat, 07 Nov 2009 03:29:47 +0000

CGA adapter / SCART has great advantages as it does not require separate power source and that uses very few external components, which can be easily adapted in the SCART connector. The signals from R, G and B pins of the CGA’s board are converted from TTL levels to SCART levels with resistors R4, R5 [...]

UHF antenna amplifier

ElectroSchematics.com — Tue, 24 Jun 2008 08:54:26 +0000

This amplifier circuit is used to amplify TV signals in UHF range. It uses a low-noise transistor and gives 10 to 15 dB amplification in the frequency range from 400 MHz to 850 MHz. The transistor must be shielded from the input components and in constructing this circuit, the wirings must be as short as [...]

Simple cable tv amplifier

ElectroSchematics.com — Wed, 18 Jun 2008 15:27:44 +0000

This cable tv amplifier is a rf-amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si T1 transistor, T2 is working as an emitter follower. The feedback bias is determined by R3 and R4. The total gain of this tv [...]
