... Problem 3 An engineer designs a power supply that consists of a transformer, a full-wave, 4diode bridge rectifier and a smoothing capacitor. The nominal load current is 1.2 A. By what percentage will the ripple voltage increase/decrease if the supply is used with an actual load of 1.5 A? Assume the ...

... We can also reduce the Flicker noise (proportional to 1/f) to negligible values if we operate the SET in the rf-domain Operating the SET at high frequencies ( 100MHz 1GHz ) will reduce the Flicker noise to values that can be ignored and at low frequencies ( 1MHz ) a feedback can compensate for ...

Measure resistance with a microcontroller
... Next, define the scale measurement or digital value within the microcontroller. The nominal value of the DUT (device under test) should be close to half of the scale selected. Thus, you should set the full-range scale from 0 Ω to 100 Ω. If you use a microcontroller that contains a 10-bit ADC, it wil ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
