“Understanding Modern Electronics” S:1 E:14 More Fun with Op-Amps

S:1 E:14 More Fun with Op-Amps Explore peak detectors that “remember” the maximum voltage reached, as well as Schmitt triggers whose output retain their value until the input changes sufficiently to “trigger” a change in the output. Use these concepts to design a practical circuit: an alarm to warn if your freezer’s temperature has been above freezing.
