Here we specify the slopes of the rising and falling segments +(as always \, in units per cycle). We then make a triangle wave with +a corner at (0 \, 0) and another one \, placed somewhere within the +cycle. The slopes of the two lines determine the second point \, which +will have an x value of t/(s+t) (if we let s denote the rising slope +and t the falling one \, both as positive numbers). The y value is +st/(s+t). If we wish instead to specify the corner location (x \, y) +(with x in cycles \, 0<x<1) we set s = y/x and t = y/(1-x). The DC +value is y/2.; +#X connect 5 0 15 1; +#X connect 6 0 5 0; +#X connect 7 0 18 1; +#X connect 8 0 7 0; +#X connect 9 0 10 0; +#X connect 10 0 4 0; +#X connect 11 0 15 0; +#X connect 11 0 16 0; +#X connect 12 0 11 0; +#X connect 15 0 19 0; +#X connect 16 0 17 0; +#X connect 17 0 18 0; +#X connect 18 0 19 1; +#X connect 19 0 3 0; +#X connect 19 0 4 0; |
