Fundamentals of Mixed Signals and Sensors  Topic: ADC DAC Solve for the output of the DAC in figure below if the waveforms representing a sequence of 4-bit numbers in figure below are applied to the inputs. Input D0 is the least significant bit (LSB).   Reverse the input waveforms to the DAC in the figure (D3 to D0, D2 to D1, D1 to D2, D0 to D3) and determine the output.

The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage. Write any two types of filter circuit in rectifier providing the necessary Sketch, explanation
