What are half wave symmetric waves ?

AI Thread Summary
Half wave symmetric waves are defined by the property f(t-T/2) = -f(t), indicating that the wave is inverted over half of its period. To determine if a wave exhibits half wave symmetry, one must analyze its mathematical representation and check for this specific condition. The discussion emphasizes the need for clarity on how to identify this symmetry in various waveforms. Understanding the definition and applying it to specific examples can aid in grasping the concept. Further exploration of practical examples may enhance comprehension of half wave symmetric waves.

what are half wave symmetric waves ?

hello friends...i m studying signal n system...i havnt find suitable info about half wave symmetric waves from anywhere...i need to understand that how to find whether any wave is half wave symmetric or not...please help me friends ...

Have you looked at the definition of half wave symmetry :

f(t-T/2) = -f(t)

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 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
