A method and apparatus by which ATSC-receiver-compatible digital TV signals may be generated without most of the discrete and/or high-complexity components required by the ATSC specification, through the use of a precomputation of digital filter coefficients that consolidates multiple functions into a single step, and through the derivation of multiple required carrier frequencies using a single oscillator circuit. The resulting design meets all requirements of the ATSC specification, reducing significantly the cost of the necessary signal-processing functions, and in a manner compatible with the VLSI (very-large-scale-integrated) circuit technologies of the field.
