Figure 4. — Effect of stimulation pulses on oscillations with constant amplitude envelope. Targeted oscillations (−), modulated (suppressed/amplified) oscillations (−), reference signal for amplification (- -), optimal stimulation sequence (–) Targeted signal, modulated signal, and Wavelet scalograms of the modulated signal during a transition from off- to on-stimulation are shown for sequences with the following characteristics: (a), (b) pulses of adjustable amplitude (max. amplitude $a_{s}$ = 2.5 mA) that suppress the targeted oscillations; (c), (d) pulses of adjustable amplitude (max. amplitude $a_{s}$ = 0.4 mA) that suppress the targeted oscillations; (e), (f) pulses with the binary amplitude constraint that suppress the targeted oscillations; (g), (h) pulses of adjustable amplitude (max. amplitude $a_{s}$ = 2.5 mA) that amplify the targeted oscillations.
