Abstract:
1. A system for equalizing signal data, said system comprising: an antenna that receives said signal data, wherein said signal data comprises a luminance carrier comprising a luminance channel and a chrominance carrier comprising a chrominance channel; an analog-to-digital converter coupled to said antenna that converts the received signal data to digital signal data; an instruction memory storing digital equalizer instructions; and a digital equalizer system, coupled to said memory and said analog-to-digital converter, wherein said digital equalizer system processes said digital equalizer instructions to: wherein said signal data comprises an analog television signal and said analog television signal comprises a blanking period and said blanking period comprises an Hsync, a front porch, and a back porch, wherein said Hsync, said front porch, and said back porch comprise an amplitude of said analog television signal at a predetermined value for a predetermined amount of time, wherein said digital equalizer comprises a luminance equalizer, wherein said luminance equalizer equalizes said luminance channel, and wherein said luminance equalizer: calculates a channel estimate by dividing said received sample mean by a stored sample mean.
