Some of the best digital SRCs nulled out in the -40 dB range.
I worked with an analog computer in the early 1960's. The individual "operational amplifiers" were "chopper stabilized" and were rated to be accurate to 0.01%. By the time you were done solving a problem, e.g. integrating the rocket equation for an ABM system, you would be very lucky if the accuracy was 0.1%.
This machine was part of a "Hybrid" computer. You can see what this looked like in the attached brochure. A real fun teenage summer job, for which I was paid the minimum wage at the time of $1.00 / hour. (Years later, I learned that my boss charged the U.S. Air Force $7.00 / hour.)
