please help with work shown

1. A decoder is to be embedded into a mux which is capable of multiplexing m channels to output 16 lines. The decoder has been decided to be 1-of-32. 1. How many incoming lines are there for the decoder? Explain. 2. What is the value of m ? Explain. 3. What is the total number of lines going into the mux to be multiplexed? Explain. 4. Sketch the mux. 2. Convert x=p(q+rs) into 1. a NAND-only circuit. 2. a NOR-only circuit. Draw the circuit. 3. Given table 4-6 for a 4-to-2 encoder, on page 42 of Lee text, with the following encoding scheme with respect to each activated incoming line: d0 only >01,d1 only >11,d2 only ->00, d3 only ->10, d0 \& d3 only -> 01, d1 \& d2 only ->
