Question 2: Calculate the output of the circuit if the Op Amp is ideal. Question 3: What is the output voltage of the following amplification circuit? Question 4: For the circuit of the figure, draw the output waveform and calculate the output voltage at t = 25ms. Question 5: During testing of an operational amplifier signals of equal magnitude and opposite signs are applied to the two input terminals of the device. In this case, what kind of gain is being measured? Question 6: In a real Op Amp, if the voltage with respect to ground of the inverting terminal is 1mV and that of the noninverting terminal is 2mV, and if the output voltage is 10.01V and the gain 10,000, what is the common-mode rejection ratio? Question 7: Design the instrumentation amplifier of the figure to provide a gain that can be varied over the range of 2 to 1000 utilizing a 100KOhm variable resistance. =================== For more on Signal Amplification watch this video https://youtu.be/3_vGaflHFE4 =================== To contact me send message to my WhatsApp: +55 32 999 163 417 Para entrar em contato comigo envie mensagem para meu WhatsApp: +55 32 999 163 417
