Negative amplitude means the signal is attenuated relative to a reference point, so if you see e.g. -20dB, it means the signal is 1/10th of the reference value. dB on it's own is unitless, so you will see things like dBm (relative to 1mW â 0dB = 1mW), or dBV (relative to 1V â 0dB = 1V).
In Colorado, the offer is valid at the Denver Zoo and the Denver Art Museum. However, the Denver Art Museum is Sunday only, because they already offer free admission to everyone on the first Saturday of the month. This list does change, so check the Museums on Us website, before you go.
Bill & Alice Nix Petting Zoo. In the Fall of 2006, the College of Agriculture began a free petting zoo on our farm at our beef barn facility. What began as a once per year event has now become seasonal staple of our community. Prior to the official petting zooâs opening, schools randomly contacted the farm and were given tours primarily of the swine and sheep areas.
