Electronics and Communication Measurement And Instrumentation Difficulty: Medium

A series LCR circuit consisting of R = 10 Ω, |X L | = 20 Ω and |X C | = 20 Ω is connected across an a.c. supply of 200 V rms. The rms voltage across the capacitor is In a bipolar transistor at room temperature if the emitter current is doubled the voltage across its base-emitter junction is An analog voltage of 3.41 V is converted into 8-bit digital form by an A/D converter with a reference voltage of 5 V. The digital output is If contents of the accumulator in 8085 are 81 H and carry flag is '0', find accumulator contents after executing the instruction RRC? The phase margin of a system with the open-loop transfer function $$G\left( s \right)H\left( s \right) = \frac{{\left( {1 - s} \right)}}{{\left( {1 + s} \right)\left( {2 + s} \right)}}$$
