SUMMARY

The amplifier discussed increases the peak-to-peak voltage from 1 V to 20 V, resulting in a gain of 26 dB. This calculation is derived using the formula dB = 20 log10 (Vout/Vin). The correct values were substituted into the equation, confirming the gain as 26 dB. This method provides a straightforward approach to calculating amplifier gain in decibels.

PREREQUISITES
  • Understanding of voltage levels (Vout and Vin)
  • Familiarity with logarithmic calculations
  • Basic knowledge of decibel (dB) measurement
  • Experience with amplifier concepts
NEXT STEPS

An amplifier increases the peak-to-peak voltage of a signal from 1 V to 20 V. What is the amplifier's gain in dB?



dB = 20 log10 (Vout/Vin)



In this case dB = 20 log10 (20/1) I'm not sure :/

Looks like you filled out the equation correctly - just have to 'plug-n-chug'. I get 26dB.
 
yay thanks
