&lt;p&gt;&lt;b&gt;Página nueva&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Assumptions:&lt;br /&gt;
* All of the opamps are ideal (A&amp;lt;sub&amp;gt;d&amp;lt;/sub&amp;gt;=∞, A&amp;lt;sub&amp;gt;cm&amp;lt;/sub&amp;gt;=0, I&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt;=0).&lt;br /&gt;

* The two LDRs are exposed to the same amount of light from the LED.&lt;br /&gt;
* The LDRs are shielded from ambient light.&lt;br /&gt;
&lt;br /&gt;
Because I&amp;lt;sub&amp;gt;in&amp;lt;/sub&amp;gt;=0, all of the current from the control input continues through the bottom LDR, to the -15V supply. &lt;br /&gt;
&lt;br /&gt;
V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt; / 10k = 15 / R&amp;lt;sub&amp;gt;LDR&amp;lt;/sub&amp;gt;, so &amp;lt;br&amp;gt;&lt;br /&gt;
R&amp;lt;sub&amp;gt;LDR&amp;lt;/sub&amp;gt; = (15 * 10k) / V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt; &amp;lt;br&amp;gt;&lt;br /&gt;
R&amp;lt;sub&amp;gt;LDR&amp;lt;/sub&amp;gt; = 150k / V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt;  (eq 1)&lt;br /&gt;
&lt;br /&gt;
We assume the two LDRs have the same resistance at all times.&lt;br /&gt;
&lt;br /&gt;
The audio path is composed of two gains, cascaded. &lt;br /&gt;
&lt;br /&gt;
A&amp;lt;sub&amp;gt;v1&amp;lt;/sub&amp;gt;: The voltage gain from the AUDIO INPUT terminal to the left terminal of the upper LDR. &amp;lt;br&amp;gt;&lt;br /&gt;
A&amp;lt;sub&amp;gt;v2&amp;lt;/sub&amp;gt;: The voltage gain from the left terminal of the upper LDR to the OUTPUT terminal, assuming the output is unloaded.&lt;br /&gt;
&lt;br /&gt;
A&amp;lt;sub&amp;gt;v1&amp;lt;/sub&amp;gt; = -1 * 150k / 150k &amp;lt;br&amp;gt;&lt;br /&gt;
A&amp;lt;sub&amp;gt;v1&amp;lt;/sub&amp;gt; = -1&lt;br /&gt;
&lt;br /&gt;
A&amp;lt;sub&amp;gt;v2&amp;lt;/sub&amp;gt; =  -1 * 150k / R&amp;lt;sub&amp;gt;LDR&amp;lt;/sub&amp;gt;                    (eq 2)&lt;br /&gt;
&lt;br /&gt;
Substituting the expression for R&amp;lt;sub&amp;gt;LDR&amp;lt;/sub&amp;gt; from (eq 1) into (eq 2), we get:&lt;br /&gt;
&lt;br /&gt;
A&amp;lt;sub&amp;gt;v2&amp;lt;/sub&amp;gt; =  -150k / (150k / V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt;), or &amp;lt;br&amp;gt;&lt;br /&gt;
A&amp;lt;sub&amp;gt;v2&amp;lt;/sub&amp;gt; =  -V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore,&lt;br /&gt;
&lt;br /&gt;
A&amp;lt;sub&amp;gt;total&amp;lt;/sub&amp;gt; = A&amp;lt;sub&amp;gt;v1&amp;lt;/sub&amp;gt; * A&amp;lt;sub&amp;gt;v2&amp;lt;/sub&amp;gt; &amp;lt;br&amp;gt;&lt;br /&gt;
A&amp;lt;sub&amp;gt;total&amp;lt;/sub&amp;gt; = -1 * -V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt; &amp;lt;br&amp;gt;&lt;br /&gt;
A&amp;lt;sub&amp;gt;total&amp;lt;/sub&amp;gt; = V&amp;lt;sub&amp;gt;control&amp;lt;/sub&amp;gt;&lt;/div&gt;</summary>
