Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

In today’s world, power amplifiers are used in many devices for a wide variety of applications. In general, an amplifier takes a low power input and regenerates the signal at several watts higher.

Understand the basic audio components of a Hi-Fi stereo system so you know what to look for when shopping for audiophile equipment. Amplifier. Amp. Preamp. Integrated amp. Phono stage. Tube amplifier.

Audio is an integral part of portable consumer electronic devices. An integrated headphone audio power amplifier helps amplify the low-power baseband audio signals to drive crisp and clear audio when ...

Monolithic amplifiers are now cheaper to buy and provide a much-improved performance for little cost. This app note demonstrates different circuits that can be created with monolithic op-amps. To view ...

If you’re building a hi-fi system, amplification is a necessary cog in the chain. While your source (turntable, streamer etc) plays your music and your speakers output it, the middle-man amplifier ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...
