Perform AC Analysis to plot the response of the preamplifier

Perform AC Analysis to plot the response of the preamplifier. Take the Screenshots of the response and show the approximation of RIAA equalization curve. How do you do this in Multisim 14,0. When I did analysis using AC analysis the plot did not have voltage and frequency needed for the lab.

Solution

Ans: here iam expalining about the analysis to plot the response of the preamplifier:

Frequency of the source doesn’t matter. This is because the AC Analysis will sweep the frequency anyways so any frequency assigned to the AC_VOLTAGE source will have no play in the AC Analysis. The frequency will, of course, influence Transient Analyses and other similar simulations

The European version of the RIAA curve used in making the record. Why was this curve imposed on the records. Using it improved the signal-to-noise ratio of the record by boosting the highs going to the cutting head, while greatly extending the play-back time by cutting the lows. The end result was a fairly even grove cut, regardless of the frequency.
