the open-loop voltage amplification of the general-purpose operational amplifier is above 80dB, and the output voltage of the op amp is limited, generally between 10 V and 14 V. Therefore, the differential mode input voltage of the op amp is less than 1mV, and the potential of the two ...
The purpose of this report is to discuss and to illustrate how the application of an operational amplifier in a recording system using piezoelectric transducers and long coaxial cable lengths overcomes the problem of low signal due to cable attenuation. (Author)Wilson, R. D...
