We can help you in a heartbeat!<\/p>\n<p>A new <a href=\"http:\/\/testandmeasure.org\">website<\/a> that we have launched in beta is aimed at being a valuable resource for <a href=\"https:\/\/digilent.com\/shop\/waveforms-previously-waveforms-2015\/\">WaveForms<\/a> example workspaces, data, and projects. Today, I am highlighting one asset from the <a href=\"http:\/\/testandmeasure.org\">site<\/a>, a&nbsp;<a href=\"https:\/\/testandmeasure.org\/#\/category\/signals\/sample-signal-heartbeat-7cf4de16\">sample signal of a human heartbeat pulse<\/a>!<\/p>\n<p>Using <a href=\"https:\/\/digilent.com\/shop\/waveforms-previously-waveforms-2015\/\">WaveForms<\/a>, you can capture signals and export the data to be used at a later time or import a known signal to test a circuit&#8217;s response. For example, this pulse signal could be useful in testing a biomedical application that has a heartbeat pulse for an input. This signal can be imported into the Waveform Generator and used as an input if having a human connected is inconvenient or if the test requires some repeated signal over time. A known pulse signal could also provide valuable reference in the Oscilloscope to compare a new or other recorded signal.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-26209\" src=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2018\/12\/2018-12-07-15_46_42-Window.png\" alt=\"\" width=\"419\" height=\"319\" srcset=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2018\/12\/2018-12-07-15_46_42-Window.png 419w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2018\/12\/2018-12-07-15_46_42-Window-290x220.png 290w\" sizes=\"auto, (max-width: 419px) 100vw, 419px\" \/><\/p>\n<p>This sample heartbeat pulse was captured using a photoresistor, a technique called \u201cphotoplethysmography\u201d which senses changes in blood reflectivity as it pulses through a finger or earlobe.
