3 Band Graphic Equalizer Circuit

The circuit illustrates the use of 3 frequencies to produce a graphic equalizer that will be used for acoustic signals.

Modular Buffer Preamplifier in Class A Operation

The circuit was designed to create a modular Class A buffer preamplifier in order to isolate stages in an audio circuit.

Linear Phase Response From 3-Way Crossover Circuit

The circuit was designed to produce a 3-way crossover circuit that will produce a linear phase response within the filters included in the circuit.

Three ECC83-Based Tube Phono Preamplifier Circuits

The three circuits were based on the vacuum tube ECC83 designed to produce phono preamplifiers in compliance with the RIAA standards.

Audio Volume Unit Meter

The circuit was designed to create a volume unit meter that would be used to measure the intensity of audio or sound level.

50 Watts Audio Power Amplifier

The circuit was originally based on the design of OSU IEEE student group which aims to produce an audio power amplifier with 50 Watts output.
