41. Most of the tonalities were generated with a circuit called a ring modulator . 42. The ring modulator was used for intense sound transformations. 43. However, the System II passed sound to the television through the RF modulator . 44. These were driven by a class B modulator with the same type of valves. 45. In combination with polarizers, it can be used as a shutter or modulator . 46. The NRD1 gene codes for the protein nardilysin, an HB-EGF modulator . 47. A polarization modulator in this instrument changes the polarization states of the laser output. 48. A Photograph of a modulator segmented into 9 pixels is shown in Figure 5. 49. Another protein important in Akt attenuation is Carboxy Terminal Modulator Protein ( CTMP ). 50. The balanced modulator output can either lead or lag the carrier's phase.
