![]() “Your inspiration will forever be in my music,” Petras shared. Petras took pause to reflect on that accomplishment while also thanking late producer/collaborator SOPHIE. “Unholy” made history earlier in the ceremony when it won best pop duo/group performance, making Petras the first openly transgender Grammy winner. The duo’s performance was introduced by Madonna, who coyly asked, “Are you ready for a little controversy?” She then added, “If they call you shocking, scandalous, troublesome, problematic, provocative, or dangerous, you are definitely onto something,” and gave thanks to all artists like Smith and Petras who are “rebels forging a new path and taking the heat for all of it … Here are two incredibly talented artists that have risen above the noise, doubt, and critics into something truly unholy.”Īfter the performance, host Trevor Noah pretended to be on the phone trying to calm down his mom. Watch Sam Smith Perform ‘Gloria,’ ‘Unholy’ With Special Guests on Saturday Night Live With Smith appearing like a devilish ringleader and Petras locked in a cage in front of a backline of fire, the explosive performance took cues from the song’s sultry music video, which was staged in an underground sex club and featured porn stars and characters from RuPaul’s Drag Race.Ģ023 Grammys: The Winners, Losers and Best Performances 5) with a seductive performance of their global smash hit “Unholy.” Sam Smith and Kim Petras offered one of the raciest moments of the 65th annual Grammys tonight (Feb.

These scales are calledthe radially scaled parameters and they are both very important and often overlooked.With these scales, you can determine such factors as VSWR (both as a ratioand in decibels), return loss in decibels, voltage or current reflection coefficient, andthe power reflection coefficient.The reflection coefficient () is defined as the ratio of the reflected signal to theincident signal. Notice that the upper half-circle is calibrated 0 to 180 and the bottomhalf-circle is calibrated 0 to 180, reflecting inductive or capacitive reactancesituations, respectively.Radially scaled parametersThere are six scales laid out on five lines (“D” through “G” in Fig. All rights reserved.Any use is subject to the Terms of Use as given at the website.Ĥ72 The Smith chartThe Smith chartcircuit at the load end of the line reflects the signal back toward the generator180 out of phase with the incident signal an open line (i.e., infinite impedance)reflects the signal back to the generator in phase (i.e., 0) with the incident signal.This is shown on the Smith chart because both scales start at 0 on the righthandend of the pure resistance line, which corresponds to an infinite resistance,and it goes half-way around the circle to 180 at the 0-end of the pure resistanceline. Recall from transmission line theory that a shortDownloaded from Digital Engineering Library McGraw-Hill (© 2004 The McGraw-Hill Companies. These scales are the relative phase angle betweenreflected and incident waves. Thus, 0.12 on the outer scale corresponds to (0.50–0.12) or 0.38 on the innerscale.The angle of transmission coefficient and angle of reflection coefficient scalesare shown in circle “C” in Fig. These two scales are complementary at allpoints. The outer scale is calibrated clockwise and it represents wavelengthstoward the generator the inner scale is calibrated counterclockwise and itrepresents wavelengths toward the load.
