  • Abstract
    A simple modification of conventional intensity recorders substantially increased their inherently low dynamic range at a slight sacrifice of S/N processing gain. The implemented modification consisted of a square wave modulation of the gain of the recorder amplifier. It was tested on two standard intensity recorders with satisfactory results presented here. Some theoretical aspects are discussed in the Appendix.
