A continuous-time signal x(t) = cos(φ(t)), where φ(t) = ω0 + sin(ω0t), is to be sampled at a rate fs.What is the system's Nyquist sample rate if ω0 = 1000/(2π) rad/sec.?
Consider an LTI(linear,time-invariant) system with input x(t) and output y(t). Suppose you know(measure) the step response, tha is , for x(t) =u(t), you know that y(t) = 2e^(-0.5t)*u(t). Find the output for the following different inputs
Design a sequence generator circuit with 4 outputs W,X,Y and Z. The circuit should generate the following sequence of output patterns: 0001, 0011, 1100, 1000. After 1000, the circuit should repeat the sequence starting at 0001 again.
Sketch the equivalent circuit and phasor diagram for the no-load conditions and, assuming operation is in the step down mode, determine (a)the exciting current; (b)the core loss component of the exciting current; (c)the magnetizing current; (d)the..
determine the efficiency of a high frequency induction furnace which takes 10 minutes to melt 1.815 kg of aluminium the input of the furnace being 5 KW and the initial temperature 15 deg.
A) Design a sequence detector using D flip-flops to detect the sequence 1101with the overlapping permitted. B) Design a synchronous counter using J-K flip-flops that hasthe following sequence:- 000,010,101,110 and repeat.
Given the function f(X1, X2, X3, X4) = fm(0,1,4,6,911,14,15). Implement the function f using a 4:1 multiplexer. Assume that inputs are available in both forms: complemented and non-complemented. Use only the multiplexer.
Study code acquisition in frequncy hopping spread spectrum communication systems.Describe and explain why it is necessary.Design and demonstrate a code acqusition method.
In a step-down converter, consider all components to be ideal. Let v_0 = V_0 be held constant at 5 V by controlling the switch duty ratio D. Calculate the minimum inductance L required to keep the converter operation
How to calculate the emf induced by an alternative magnetic field in a straight-line conductor of lenght L.
The doping level of N-type semiconductor is Nd= 5^19 cm^-3. Determine the room tempature position of the Fermi level ( with respect to the bottom of the comduction band) if the semiconductor is A). Si (Nc=2.86^19cm^-3)
Two DTEs are communicating via modems and RS-232C interfaces over a half duplex link. Data transmission is one directional with each message of length M. After a message is transmitted, the sender waits for a CTS message.
A temperature transmitter has an input range of 0 to 100 degrees celsius, an output range of 4 to 20 mA, and anaccuracy of ± 0.5%. The ideal transmitter has a linear output from 4 mA at 0 degrees celsius to 20 mA at 100 degrees celsius.
