hi
please note to attached file.
1) what is the role of R1 resistor and why this value is selected for it?
2) for opamp, there are restiction as slew rate and gbw(gain band width) and noise. for a special signal career and data ( their frequency and amplitudes),what limits are settle on opamp?
namely for supposed f_carrier and f_data, what must be gbw of opamp?
for supposed amplitude of data signal, what must be slew rate of opamp?
thanks
