<p>Sample &amp; Hold Circuits are ICs (integrated circuits) that sample the voltage of ani input analog signal that is continuous and retain the value at a consistent level for an amount of time set by the user. This generation of the sample of the input signal is called sampling time</p><h2>What are sample &amp; hold circuits used for?</h2><p>Sample &amp; hold circuits are primarily used in linear systems to compare voltage generated via a DAC (digital-to-analog converter). The circuit tests values until the voltage is equal. Each value is then sampled and held utilising a sample clock.</p><h3>Applications of sample & hold circuits</h3><p>Most commonly in ADCs (analog-to-digital converters)  to remove variations in the input signal. They are utilised in musical instruments such as synthesizers to impart effects on randomly to played notes.</p><p>Sample and hold circuits are also used in other applications such as;</p><ul><li>Digital Voltmeters</li><li>Analog Signal Processing</li><li>Data Conversion Systems</li></ul>
