  2. 1.) Waveform checking procedures? 2.) Testing measurements and what are the terms and names? 3.) Measure impedance for input and output on each stage? how do i do this with my DMM or Oscilloscope? 4.) Time measurements? phase, pitch,frequency, period and time 5.) Frequency Response test procedures how do i do them with a function generator and a DMM or oscilloscope? 6.) Overloading the input measurements? how to measure this? 7.) Measure the Current Draw on each stage or Measuere the Current Draw of the power supply?
