The company was founded in 1988 by Mike Zaite, a.k.a. Dr. Z. Zaite grew up the child of a television repairman and learned about vacuum tubes at an early age. [1] He played the drums, and started producing tube amplifiers in his Cleveland, Ohio, shop while maintaining his day job as a medical electronic technician at G.E. [2] As the son of a TV repair shop owner, Zaite learned the ropes at the ...
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier 's characteristics and performance. The first three classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a ...
The amplitude of ECG ranges from 0.3 to 2 mV for the QRS complex, which is used to determine the interbeat interval from which the frequency is derived. The typical requirements for the amplifiers to be used in ECG include: [1] Low internal noise (<2 mV) High Input Impedance (Z in > 10 MΩ) Bandwidth ranging from 0.16–250 Hz
[10] [11] In 1988, it developed the 100 W solid-state power amplifier covering 100 MHz to 1 GHz, and by 2015 it had achieved a 50,000 W CW, class A, solid state amplifier. [ 12 ] Acquisitions
Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
