| 1 | Notice that periodic waves that are even functions of time , that is , symmetric about the time origin , can be represented by a constant and just cosine waves , while waves that are odd functions of time , that is , reversed in sign about the time origin , can be represented by just sine waves . |
| 2 | Notice that periodic waves that are even functions of time , that is , symmetric about the time origin , can be represented by a constant and just cosine waves , while waves that are odd functions of time , that is , reversed in sign about the time origin , can be represented by just sine waves . |
| 3 | Accordingly , the time origin of the square wave has been taken at one of its leading edges in arriving at the representation given by expression ( 11.2 ) . |
| 4 | It is convenient to make the wave an even function of time by choosing the time origin as shown in figure 11.2(a) . |
| 5 | In particular and Since all the b n coefficients are zero through having chosen the time origin so as to make the function even in time , the half-wave rectified sinewave of figure 11.2(a) is evidently equivalent to In other words , the half-wave rectified sinewave shown in figure 11.2(a) is equivalent to the harmonic spectrum of pure cosinewaves shown in figure 11.2 ( b ) . |
| 6 | A corollary of this last point is that the technique is likely to succeed when the signal is switched on at some moment to which the time origin may be ascribed , the inference being that the signal is zero up to time . |
