There are two pairs of these - the one used depends on the +level of the Gate.</p> +<p>Example uses:</p> +<ul> + <li> + <em>An envelope tracker</em>- use the ‘Gate Low’ track rates with + the Gate held low, and run the output through a full-wave rectifier (an ABS() + operator) to get an estimate of the level of a signal.</li> + <li> + <em>Sample and Hold</em>- run a narrow pulse wave into the gate, set the + ‘Gate High’ rates to maximum, and the ‘Gate Low’ + rates set to 0.</li> + <li> + <em>Track and Hold</em>- run a variable pulse wave into the gate, set the + ‘Gate High’ rates to 0, and the ‘Gate Low’ rates set + high.
