移频 (将选带的中心频率移动到零频) 数字低通滤波器 (防止频率混叠) 重新采样 (将采样的数据再次间隔采样,间隔的数据取决于分析的带宽,就是放大倍数

FlyweightMode

运用共享技术有效地支持大量细粒度对象的复用。系统只使用少量的对象,而这些对象都很相似,状态变化很小,可以实现对象的多次复用。由于享元模式要求

Since each of the samples are taken at equally spaced time intervals, we have a time log of what happened during the chirp. Every sample is a complex number, meaning we have captured some magnitude of power as well as the phase of the wave at that time. So, our object will theoretically appear as an increase in power in our samples. On the other hand, we can use the
