Numeric responses must be either an integer (if exact) or a real number with three decimal places, with the least significant number rounded. Do not use commas. If there are units, the integer part must be between 1 and 999. Use the following units: Ohm, kOhm, mOhm resistors, etc. Conductances: S, mS, MS, etc. Voltage: V, kV, mV, MV, etc. Current: A, mA, kA, uA, nA, etc. Power: W, mW, kW, uA, pW, etc. Time: s, hrs, ks, ms, etc.

1. Voltage amplifiers are available with Avoc = 8 V / V, Rin = 1.8 kΩ, Ro = 850 Ω. With a 12 V DC power source, each amplifier consumes 1.5 mA average current.

a. How many amplifiers do you need to cascade to get at least a 1000 voltage gain with a load resistance of 1.0 kΩ?

b.What is the voltage gain Av obtained? (Respond with a rounded whole number)

c. For the cascade connection, find the open circuit voltage gain. (Respond with a rounded whole number)

d. If you have a 1.5 mV input, how efficient is the equivalent amplifier?

e. Find the transconductance of the entire circuit.

A formula with a positive integer (less than 32 bits) and a positive decimal (number with decimal points) is expressed in the median formula. Change the given median to postfix and write a program that outputs the results of the calculation. operand ::= positive integer or positive error Positive integer ::= A number expressed as less than 32 bits consisting of 0 to 9. Positive integer representation of 0, 0100, 00934, 1056, 65535 is allowed Positive decimal ::= Positive integer...

JavaScript each item must have at least three categorical attributes and at least one numeric attribute. Write a function that counts the number of values each item attribute has. This is effectively a group-by on the item table for each column. For example: if the first attribute is colour, and its values are [ ‘red’, ‘black’, ‘white’, ‘black’, ‘red’ ], the counts for colour would be: red 2 black 2 white 1

Workco must have the following number of workers available during the next three months: month 1, 20; month 2, 16; month 3, 25. At the beginning of month 1, Workco has no workers. It costs Workco $100 to hire a worker and $50 to fire a worker. Each worker is paid a salary of $140/month. Formulate the problem of determining a hiring and firing strategy that minimizes the total cost incurred during the next three months as a MCNF problem.
