2. Apply a variable frequency square wave as the input to the noninverting voltage follower. Observe both the input and output using the two 10X probes and the dual- trace oscilloscope. If the square wave is symmetrical at about 0 VDC, adjust the input signal's amplitude until the output is almost reaching the two saturation volts. 3. Observe the input and output as the square wave signal frequency is varied from about 100 Hz to above 100 kHz. 4. Select a frequency where the rise time TSR can be easily measured. Measure this quantity along the pertinent voltage change. Calculate the slew rate S. Record your answer in Table 8-1, then compare your result against the 741 operational amplifier data in the text's Appendix C. List the appendix's data in Table 8-1. V.

Based on the observed slew rate S previously listed in Table 8-1, calculate the slew rate limiting frequency for based again on a 10 V, sinusoidal output. Record your results in Table 8-2 under the Calculated for.
