  Technology

  Analog synthesizers use analog circuitry to create electronic audio signals.  These electronic audio signals are converted into sound by a speaker using an electroacoustic transducer.  There are five main sections of a signal path in a basic subtractive analog synthesizer:
  
  1. Oscillator (VCO)
  2. Filter (VCF)
  3. Amplifier (VCA)
  4. Low Frequency Oscillator (LFO)
  5. Envelop Generator (EG/ADSR)
  
  Many of these synthesizer principles form the basis for the synthesizer technologies in the coming chapters.
