Verstärkern

Verstärkern is the dative plural form of the German noun Verstärker, which in everyday usage refers to amplifiers. In technical contexts the term denotes devices or circuits that increase the amplitude of electrical signals by drawing power from a supply and delivering a larger output signal to a load. The standard singular noun is Verstärker and the plural nominative is Verstärker; Verstärkern appears primarily in phrases such as mit den Verstärkern (with the amplifiers).

Amplifiers are used across a wide range of applications, including audio equipment, radio and communications, instrumentation, and test and measurement systems. Common types include audio amplifiers that drive speakers, RF or microwave amplifiers for transmission and reception, and operational amplifiers (op-amps) used in analog signal processing. Power amplifiers are designed to deliver higher output power, often at specific impedances, while instrumentation amplifiers emphasize precision and high input impedance for sensor signals.

Performance characteristics define design choices. Key metrics include gain (voltage, current, or power), bandwidth, distortion and linearity, noise figure, input and output impedance, and supply voltage. Efficiency and emission are central for power and radio frequency amplifiers, while stability and bandwidth are critical for feedback-based designs such as op-amps. Amplifier classes (A, B, AB, C, D, and variations) describe conduction angles and efficiency rather than a fixed feature set, guiding trade-offs between fidelity, complexity, and heat management.

Typical applications span consumer audio, broadcast and telecommunications, measurement equipment, and signal conditioning in control systems.
