Q1/B/ Determine the analog voltage output for the Figure shown below if the waveforms representing a sequence of 4-bit numbers in the Figure below are applied to the inputs. Input Do is the least significant bit (LSB), where Input Digital Signal are (Do = 0001), (D1 = 0010), (D2 = 0100) and (D3 1000).

The implementation of a 4-1 multiplexer followingthe hierarchical design technique, …Requires four 2-1 multiplexers on one level ARequires three 2-1 multiplexers on one level BRequires four 2-1 multiplexers on two levels CRequires three 2-1 multiplexers on two levels DNone of previous answers E apparently the answer is D but i dont understand why so solve this question in great detail explaining every single bit of info as i'm a complete beginner and i need to understand how to solve questions of this type. also provide small examples of how the solution would differ if the question was slightly altered.

My Signals and Systems question is attached. I don't understand how to figure out parts b and c mostly, but help with a would also be appreciated.  The problem is from Alan V. Oppenheim by Alan S. Willsky. Thank you!

Please I want to solve the question Q1&Q2&Q4

Consider a 1 into 4 de-multiplexer.The data input and selection line waveforms for the demultiplexer are given below. Draw the corresponding output waveforms (for D0 to D3). Data in SO DO D3 Note: You need to draw the waveforms on paper. Take the photo and then upload. A- B I

Peak input voltage =(from graph) ?Peak output voltage =  (from graph)?DC voltage across RL = ?ripple factor=?

Realized a 4X1 multiplexer in the block diagram shown below. What is the output equation of the given multiplexer? Also draw the circuit diagram. N.B: Follow the instruction given in the figure to choose the input and output names. "First Letter of your Name"| 10 I1 | "Third Letter of your Name" 4X1 "Second Letter of your Name MUX 12 13 B
