Answer» Right CHOICE is (c) All of the mentioned combined and applied The BEST explanation: To accentuate the CONTRIBUTION to enhancement made by high-frequency components, we have to multiply the HIGHPASS FILTER by a constant and add an offset to the highpass filter to prevent eliminating zero frequency term by filter.
