It is an EEG signal which looks very much like a random signal. I want to inject a sine wave tACS data (5s long sine wave) into it at 30s. But when I say injection, I didn't mean putting sine signal over another EEG signal. At the time 30-35 seconds, I wanted to combine the two signals via addition.
