ALEXANDRIA, VA.—As television engineers age, those brought up in the era of analog signals and the subsequent transition to digital are retiring and talking hard-earned knowledge with them. Younger ...

Even before entering the mystical realms of UHF design, radio frequency (RF) circuits come with a whole range of fun design aspects as well. A case in point can be found in transmission line ...

Connecting a 600Ω audio circuit to a 50 or 75Ω circuit or test instrument requires an impedance-matching circuit or, when isolation of the circuits is necessary, a transformer. Both approaches offer ...

The single op-amp differential amplifier shown in Figure 1 is often used as an audio balanced line receiver. Obtaining high common-mode rejection is a critical requirement that requires four ...

The accuracy and versatility makes the precision analyzers the ideal choice for many different tasks and applications including passive component design, dielectric material characterisation and ...

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 ...

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 ...

Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...
