ABSTRACT:
Circuit and method for generating a ramp signal having an incrementally changing slope. The invention is particularly useful for ramping magnetic recording bias or erase signals by providing a relatively slow slope within the non-linear region of the magnetic medium characteristic while providing a relatively steep slope in the linear region to reduce recording of disturbing "pop" signals.
