<p>The data transmission rate in a cable telemetry system is improved by preconditioning an encoded data signal prior to discriminating and decoding it with a filter/amplifier 15 employing an operational amplifier 20 having a noninverting input connected to receive the data signal, an inverting input which is grounded through a series connected resistance R1 and capacitance C1 and an output which is feedback connected to said inverting input by a resistance R2.</p> |
