Title: Signals processing of effective narrow band signal and noise - having demodulator formed by sampling with square wave phased pulses in two separate circuit paths
Inventor: REBMANN VOLKMAR DIPL ING
IPC: H04B1/10
Filed: 1991-10-22
Abstract: The signal processing method involves using a mixing circuit to demodulate a signal that consists of a broad band noise signal and a superimposed narrow band effective signal, e.g. a radio data signal. The original signal (IN) is distributed between two circuit paths (Z1,Z2), each of which has a switching element (S1,S2), and with one of them having an inverter. The switches are controlled by out of phase square wave signals that define four periods (t1-t4). The output (OUT) is then received by a frequency selective fitter. ADVANTAGE - Simple and cost effective means of separating out effective component.

(III) is a free-running powder and is dosed into the heating zone mechanically, by injection with a carrier gas or through a cavity in an electric arc electrode or by embedding it homogeneously in an electric arc electrode, pref. the consumable electrode. Before stage (2), (III) may be mixed with fresh starting material, pref. a finely-divided, e.g. free-running form, to give a homogeneous prod.. ADVANTAGE - The (II) yield is increased by 25-40% by a relatively economical and very simple method.
