    Graduate How can a digital to analogue converter be designed to produce a squared output?

    How can you design a digital to analogue converter such that it has a squared output. i.e. the analog equivalent of the digital step is smaller at the lower voltage levels than at the higher voltage levels

    Undergrad Thevenin Equivalent Circuits with Dependent Source

    May anyone please help with the method of getting Thevenin Equivalent resistance (RTH) for the attached circuit. I have already found VTH to be 8V. Sim

    Sound wave no idea how to do it

    (e) The speed of the traveling wave is given by v = λf = (2.78 m)(7.96Hz) = 22.13 m/s is this correct? it seems to me the wavelength λ = 2pi/k or 2pi/3.4m = 1.85m thus v=1.85m * 7.96Hz = 14.70m/s comments? Thanks! you are right, didn't notice the mistake.

    Sound wave no idea how to do it

    From what I have seen in the maths 11218 exam I would think very close

    Sound wave no idea how to do it

    I recognise the exam is tommorow so here is what I got from another source. Solution: Visualize: What does the third harmonic mode look like ? y(x,t) = (5.60cm) sin [(0.0340 rad/cm)x] sin [(50.0 rad/s)t] Compare with standing wave expression y = 2A sin kx sin ωt λ3 L (a) Recall that...
