Composite Video Output Circuit: Get Ideas & Solutions

AI Thread Summary
The discussion focuses on generating a composite video signal, specifically for use with a television display in a microprocessor project. Participants mention the availability of chips that can generate composite video signals, including those used in NTSC test instruments. The original poster seeks a color composite video signal and is interested in using a television instead of a computer monitor. Questions arise about the television's baseband composite video input and its connector type. A reference to an application note from Maxim is provided for further guidance on the topic.

Hey Guys,

Does anyone have a general idea of the circuit needed to generate a composite video signal?

There are chips that generate composit video for you. Is that what you mean? There are some that are used in NTSC test instruments too, with built-in test patterns.

What is your application? Generate composite video from what? R-B-B-syncs?

Yes. To be more specific, I need a color composite video signal. I would like to use a television for a display for a microprocessor system that I am building. I could use a normal computer monitor but I would like to experiment with a television for a display first.

And your TV has a baseband composite video input? What is the connector for it?
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
