When pressure is applied to a localized area of the body for an extended time, the resulting loss of blood flow and subsequent reperfusion to the tissue causes cell death and a pressure ulcer develops ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

As data-communication speeds increase beyond 3 Gbps, signal integrity becomes crucial for successful data transmission. Board designers try to eliminate every impedance mismatch along the high-speed ...

Loudspeaker manufacturers sometimes exaggerate the specifications of their products to make them look better than they really are. Some are more honest than others in this regard. The focus of this ...

As you probably know if you've been shopping for cables, coax for most video applications is "75 ohm" coax–but what the heck does that mean, anyway? This article is a short, non-technical explanation ...

When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...

Ohms are one of the specs that both speaker and receiver manufacturers use to give you an idea about their performance.
