Module 4 Amplifiers Amplifier Circuits Introduction to Impedance and Bandwidth Control. What you'll Learn in Module 4. Modified Response Curves Section Introduction to Impedance and Previous modules Bandwidth Control. have concentrated on Recognise the need for changing the producing a flat shape of an Amplifier 's frequency response. frequency response over the required Section Input Compensation. audio frequency Describe typical input correction Circuits . range. It is sometimes necessary however, to Section Amplifier Controls. modify the flat Describe typical tone control Circuits . response of an audio Amplifier by making Section Amplifiers and Impedance.
between the voltage amplifier and the power amplifier stages, The value of C1 is chosen to pass the higher audio frequencies, this has the effect of progressively reducing the higher frequencies as the variable resistor slider is adjusted towards the bottom end of the tone control, The minimum level of attenuation
