    of a “PSO” also known as a RC Oscillator circuit. fig. 1.3 Vector Diagram To overcome the circuit losses, the gain of the amplifier must be sufficient. The resistor-capacitor combination in the RC Oscillator circuit also acts as an attenuator and produces attenuation of -1/29th ( Vo/Vi = β ) per stage. Therefore, in our three stage RC network above the amplifier, gain must be greater than 29. fig. 1.4 Phase Shift and

    signal into the instrumentation amplifier circuit. C.Instrumentation Amplifiers The amplitude of analog brainwaves is in between the range of 150 – 250 micro volts (μV). This is very low. For processing, at least amplitude above 2 volt is needed. For this a high gain and low noise amplifier is needed. For that instrumentation amplifier with high gain and high CMRR ratio is employed. Here one operational is not enough to produce this much high gain. So a series of amplifier is cascaded to give required

    1900’s. But suddenly in the mid of the 20th century, due to the inclusion of “Distortion” the rock music scenario achieved new heights. Now rock guitarists began intentionally "doctoring" amplifiers and speakers in order to create even harsher distortion. Guitarist Link Wray began intentionally manipulating his amplifiers vacuum tubes to create a "noisy" and "dirty” sound for his solos after a coincidence. Wray also made some holes in his speaker cones with pencils to further distort his tone. In 1966
