Generic Counter with a Stop Value Say that we must design a counter that starts at x min and stops (and remains there) when x max is reached, only returning to the initial value and running again after a reset pulse is applied to the circuit. As in section 11.7.1, the counter must have an enable input (ena) that allows the counter to run when asserted or holds it otherwise.
(a) Draw a Moore-type state transition diagram for this counter modeled as a category 3 machine.
(b) Does the number of states depend on the counting range?
(c) Does the number of flip-flops depend on the counting range? How many are needed to build your machine with x min = 1 and x max = 200?
(d) Is it advantageous or necessary to use the FSM approach to design counters in general?
An input signal x(t) = cosωct is sampled by an ideal sampling function with ωs= 1.5 ωc. The sampled signal is then filtered with an ideal low pass filter H(ω)= rect(ω/1,5ωc) to form an output signal y(t) a. Sketch the fourier transform of the sampl..
design a program for a microcontroller that takes in an input for hundreds, tens and ones in the form of a7 segment display. The user holds down either of the three buttons to increment the hunreds, tens or ones position - which is shown to be inc..

Prove that the ratio of depth to width of the strongest beam that can be cut from a circular log of wood having diameter d is 1.414
a) Find the general solution of the homogeneous ODE (the left hand side) and call it yh. b) Verify that yp= -0.5tcos(3t) is a solution.. i.e show that yp" + 9yp'= 3sin(3t). c) Construct the general solution of this ODE y=yh+yp
How can this relationship be interpreted at the pinch-off point, where the charge density approaches zero?
