<p>TRIMMING RESISTANCES IN SYMMETRICAL POLYPHASE NETWORKS A symmetrical polyphase network consists of a ring of series-connected alternate resistors and capacitors, with junction points therebetween alternately forming inputs and outputs of the network. For example there are four resistors and four capacitors. The resistors are trimmed so that the product of the resistance and the capacitance of the components connected to each respective output is equal to a product RC, R and C being the nominal resistance and capacitance of the resistors and capacitors.</p> |
