Method and apparatus for carrying out vibratory seismic operations and processing seismic records, involving generating a square wave analog sweep signal for driving a vibrator, generating a square wave analog, or 1 bit digitized transmitted signal, digitizing the received signal to 1 bit, and correlating the 1 bit digitized received signal with the 1 bit digitized transmitted signal, and stacking a plurality of such 1 bit correlograms. Simple logic means are disclosed for performing a 1 bit x 1 bit correlation. Means are disclosed for generating a square wave analog sweep signal.
