bode plot is representation of a system graphicaly using frequency response and the unit of decibell.
cos it's a plot it needs to be called a plot
You apply different frequencies at constant voltage to the amplifier and measure the output voltage at each frequency and put a dot on graph paper. For an audio amp, use steps of 500 hz.
you just need to find the problem lets say 5 and plot it onto a grid or graph and voila you got your answer...
it means you put a dot on the graph where they tell you to. Jezebella:)
