i just got my midterm 2 back. it doesn’t have work as of now because we have to do it on separate piece of paper during the exam. There r two parts about 6 questions. Please help me and show all the s

a common-emitter transistor amplifier has a base current change of 15 microamperes and a collector current change of 200 microamperes. The Load resistance is 50K ohms with an input resistance of 1K oh

What are the rules for determining the frequency range of low-and high-pass filters?

what is the steps to derive the design?

(6 marks) (c) Sketch a graph of Vo against Vs for the circuit shown below, and explain how it operates to stabilise the output voltage Vo when the supply Vs changes. Determine the following

Given a RC low-pass filter and the values of the resistor, the capacitor and a frequency located within the band-pass, is it possible to determine the db loss and the phase angle at that frequency, if

Solve the following difference equation using Z-transforms. a.) y(k) + 3y(k 1) + 2y(k 2) = x(k 1) + 3x(k 2) Given x(k) = u(k) and y(-1) = 1, y(-2) = 2 b.) y(k +1) y(k) = k^2 ; y(0) = 1

please answer the prolem on attach assignment ( course ECE171)
