Procedures for computer analysis of power specta in behaving subjects

Two computer programs for analysis of EEG data are described. Both programs are coded in FORTRAN and were written to be compatible with the University of Houston ESSL hybrid facility. The first of these is an analog-to-digital conversion program (ATOD), and the second (PWRSPC) computes power spectra for the data converted. Theoretical and practical issues involved with such data processing are discussed, and examples of output spectra are presented.
