Differential and Integral Counting Block for Spectrum Stabilizers
The operation of most present-day digital spectrum stabilizers [1–3] is based on stabilization of the position of a reference peak in a particular group of channels. The reference peak is divided into two halves by means of special digital “windows.” The difference between the readings in the “windows,” referred to their sum or square root of their sum, characterizes the degree of shifting of the reference peak from predetermined limits. Our proposed network (Fig. 1) is designed for digital spectrum stabilizers and permits the difference and sum of the readings in the “windows” to be determined either in analog or digital form. The network contains a decade three-position integral pulse counter (L3, L4, L5) and a two-position differential counter (L1, L2).
