Abstract
A decoder decodes and accurately scales so-called 'tribit' servo signals after the receipt of only one tribit pattern without the use of A.G.C. by storing the peak values of the position indicating pulses the capacitors in first and second peak-and-hold circuits and thereafter discharging both capacitors with the same time constant, activating a sample-and-hold circuit to hold the value of the output of a difference amplifier at the instant when the output of a summing amplifier falls below a predetermined value.
