Why use op amps for RF design? Traditional RF design techniques using discrete transistors have been practiced successfully for decades. RF designers who are comfortable with things “as-is” will scrutinize introduction of a new design technique using op amps. The cost of high-speed op amps, in particular, will raise eyebrows. Why replace a transistor that costs a few cents with a component that...
Tests of the superconducting cavity maser (SCM) ultra-stable frequency source have been made for the first time using a hydrogen maser for a frequency reference. In addition to characterizing the frequency stability, the sensitivity of the output frequency to several crucial parameters was determined for various operating conditions. Based on this determination, the refrigeration and thermal co...
Background & Aims: Better clinical outcomes are observed in patients who undergo thoracic procedures under thoracic epidural anesthesia (TEA). This study aimed to compare the outcome of diagnostic thoracoscopy between patients with General anaesthesia (GA) and TEA. Materials & Methods: In this randomized prospective study 30 candidates of diagnostic thoracoscopy underwent either GA (n=15) or...
