Even a fairly modest PSR spec of 40 dB isolates supply variations from the amplifier by a factor of 100. Nevertheless, high-frequency bypass capacitors (such as those in Figure 1 through Figure 7) are ...
Decibels are also used to measure the power of electrical signals. This article pertains to the measurement of sound. What Is a Decibel (dB) in Music? A decibel, ...
NAD M23 Power Measurement Table * NAD does not recommend bridging the M23 when driving 4 ohm speakers. The amp will current limit and potentially shut down. I had to reduce sweep times to even test ...
The common-mode rejection ratio (CMRR) of an op amp is the ratio of apparent change of offset resulting from a change of common-mode voltage to the applied change of common-mode voltage. It is often ...
Referring to Figure 9-10, and using the JFET Common Source voltage gain equation (gm * Rd) / (1 + gm Rs), I compute a gain of 30 (= ~30db) where as Figure 9-11 show a gain of around 13 db. What am I ...
