APPENDIX A - Conversion of the measured n.p.r. to noise
power level or signal-to-noise ratio
Deals with baseband to baseband measurements of the noise performance of simulated radio relay systems used for frequency division multiplex telephony.These measurements are additional to those already given in Part 3, Section Three of Publication 487-3-3.
