How can I identify the PUN (Pull Up Network) and PDN (Pull Down Network), if shown a schematic diagram of each.

Solutions

Expert Solution

The Pull UP Network is the network implemented with the PMOS Transistor. As PMOS passes Strong logic '1' more effectively compared to logic '0' (weak 0);

The Pull DOWN Network is implemented with the help of NMOS Transistor. As NMOS passes Strong logic '0' more effectively compared to logic '1' (weak 1);

The combination of Pull up and Pull Down Network is called as "CMOS LOGIC CIRCUIT"

The Diagram for Pull UP Network and Pull Down Network is shown Below

Mountain pull. A large mountain can slightly affect the direction of “down” as determined by a plumb line. Assume that we can model a mountain as a sphere of radius R = 3.00 km and density (mass per unit volume) 2.6 × 103 kg/m3. Assume also that we hang a 0.500m plumb line at a distance of 3R from the sphere's center and such that the sphere pulls horizontally on the lower end. How far would the lower end move...

Inoculation and Sterilization Experimental Set Up for Microbiology: I was wondering how I can do an experiment inoculating different age classes of a plant species with fungi. For example seeds can be sterilized and then inoculated and put into a sterile growth medium, but what if I wanted to do an older plant? Would that plant need to be grown in a sterilized environment up until inoculation to the age I want? Would it need to be sterilized again for...
