考虑到peak power reduction和design cost, 一般选择三角波调制! 0 H; W" U4 V+ }7 V& Z! I% F * E0 h" \' B3 a- H. n, z可以用 20×log10(SR*N*f/fm)来计算discrete peak reduction. (SR is the spread ratio, N is the harmonic, f is the fundamental frequency and fm is the modulation frequency). * b, R% V7 P6 j4 A ' e: B$ Y% K) c$ ` s$ z" y可以大家一起讨论一下!
