叠加原理在磁記录读出波形分析中的应用已經得到証明。因此每个脉冲都可当作一个孤立的瞬态来討論,并且可用线性无源网絡来减小其寬度。在很多情况下,这种讀出分辨能力的有效增强可以增記录密度。用高斯曲线作为单个讀出脉冲的一次近似。在頻率域内可以实現二次近似,并得到了傳递函数表。用傳递函数中的一个設計出网络,其解用代数公式表示。举出了一个有具体数值的实例,并给出了实驗結果。
The application of superposition principle in waveform analysis of magnetic recording readout has been proved. Therefore, each pulse can be considered as an isolated transient, and linear passive networks can be used to reduce their width. In many cases, this read-out resolution can be effectively enhanced by increasing the recording density. Gaussian curve as a single readout pulse approximation. The quadratic approximation can be achieved in the frequency domain and the transfer function table is obtained. The network is designed with one of the transfer functions, which is represented by the algebraic formula. An example with specific numerical values is given and the experimental results are given.
