Draw a circuit that operates as follows:
When power is applied to the circuit and before any push buttons are pressed all relays are de-energised and lamps extinguished.
*Relay K1 is energised and latches by pressing PB S1.*Relay K1 is de-energised by pressing PB S2.*Relay K2 is energised by pressing PB S3.*Relay K2 is de-energised by pressing PB S4.*Relay K2 cannot energise unless K1 is energised.*If relay K2 is energised, it will remain energised if K1 is de-energised.*Lamp L1 illuminates when K1 is de-energised and lamp L2 illuminates when K2 is de-energised.
1. What are some of the fundamental differences between ladder logic programs and relay logic diagrams 2. What are the advantages and disadvantages of a PLC simulation software with virtual input
Tones Input In To An Amplifier, Suppose two tones are input in to an amplifier. The tones are pure sinusoids with one at frequencies 8GHz and the other at frequency 8.03GHz,(delta f =0.03GHz).
Suppose that an inductor is formed by N turns of a conductive wire wound around a magnetic material. The magnetic material forms a circular cylinder of radius r = 10 cm, and height h = 5 cm. The inductance of the inductor turns of N is defined as:..
Design a sequence detector which produces an output 1 everytime the sequence 0101 is detected and output 0 at all other times use any flip flop.
Tell us about a time when you failed to meet a deadline. What were the repercussions?
Design a 4-bit down counter with truncated sequence that count down a truncated sequence from 1111 to 0101. On reachingthe count value 0101, the counter must preset to 1111. Also draw its timing diagram.
(a) Write f as a minterm list (that is, in the form fm(*)). (b) Write f as a canonical sum-of-products. (c) Simplify the expression from part (b). (d) Write f as a maxterm list (that is, in the form fM(*)). (e) Write f as a canonical product-of-sums...
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
Assuming interest at 8% compounded anually and insurance at 6% of book value, determine the annual usage in hours per year for which the two alternatives are equal. If annual usage is expected to be greater than this result, which of the alternati..
Source configurations can be combined to increase operating and maintenance flexibility. Sketch a hybrid primary-secondary selective system. Describe how the system would operate in the event of a. loss of one of the sources.
A conducting sphere of radius R is spinning at an angular speed ! in presence of an uniform magnetic field ˆzBo. Find the emf induced between north pole N and any point on the equator E. Hint- what is the emf induced between two end points
Consider a continuos time LTI system with step response given by ys(t) = tu(t) - (t - 2)u(t-2). Determine the output y(t) if the input to the system is given by x(t) = u(t) - u(t - 2) using complex domain (not time domain) analysis techniques.
