Hybrid microphone preamplifier with variable selection of amplifier technology
Musil, Tomáš ; Levek, Vladimír (referee) ; Háze, Jiří (advisor)
This diploma thesis deals with a basic description of dynamic and condenser microphone, its performance regarding polar patterns and a type of mechanical construction. It also describes a principle of operation of a triode. The thesis deals with selecting of a suitable type of microprocessor to control microphone preamplifier functions. Last part contains a power supply and microphone preamplifier circuits design using a semiconductor and vacuum tube technology.
