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 ...

Audio specifications fall into two broad categories: Those that are nice to know, from an enthusiast or intellectual standpoint and those that are genuinely helpful in assisting you to use, install or ...

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 ...

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 ...

Recent battery papers commonly employ interpretation models for which diffusion impedances are in series with interfacial impedance. The models are fundamentally flawed because the diffusion impedance ...

Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...
