[Eeglablist] ERSP Conversion: dB to Microvolts-squared

[Mikołaj Magnuski]

Dear Emily,

because:
dB = 10 * log10(amplitude.^2);

then you can go back to amplitude squared by performing:
amplit_sq = 10.^(dB / 10);

Assuming your ERSP are stored
in ERSP variable you can do:
ersp_amplsq = 10.^(ERSP / 10);
