Key features

• An INPUT with its SENSITIVITY ADJUST knob, from zero to max
• Envelope and threshold detectors, a frequency detector with its sample & hold, a phase locked VCO, a signal leveler and a tracking filter
• Outputs: pulse, voltage, locked osc., fundamental and const. amplitude, two of each
• A TRANSFER GATE, its in and its two outputs, opened by the envelope detector
