agram, the formula for the output signal is: <script type="math/tex">y(t) = y(t-1) + 0.125</script>
</p>
<p>We can calculate the first values of <script type="math/tex">y(t)</script>:</p>
<ul>
<li>
<script type="math/tex">y(t<0)=0</script>.</li>
<li>
<script type="math/tex">y(0) = y(-1) + 0.125 = 0.125</script>.</li>
<li>
<script type="math/tex">y(1) = y(0) + 0.125 = 2*0.125 = 0.250</script>
</li>
<li>
<script type="math/tex">y(2) = y(1) + 0.125 = 3*0.125 = 0.375</script>
</li>
<li>...</li>
<li>
