Question about VoltageA transformer has a primary voltage of 115v and a secondary voltage of 24v. If the number of turns in the primary is 345, how many turns are in the secondary?(a) 8(b) 72(c) 690 or(d) 1,653 ?
Calculating peak frequency deviation and Carson's rule bandwidth, A baseband signal has a frequency range from 50 Hz to 15.0 kHz. The signal is transmitted using frequency modulation. The FM transmitter has a modulation constant of 100 kHz per vol..
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
Determine a suitable sampling frequency. Design a notch filter to remove the 50Hz component, paying particular attention to any assumptions you have made in the design.
The frequency response of an FIR filter is H(ejw)=b0+b1*e^-jw+b2*e^-2jw. In each case below, state whether the filter is highpass, lowpass, bandpass or band stop and draw the pole zero plot.
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
Need for radical future plans to alleviate the very real problem we are faced with in New Zealand and address this problem, by providing an answer to Transpower
The transmission line has an impedance of 600 ohms and is terminated in a load of 600 ohms. The transmitter delivers an average power of 0.1 W to the input of the line.
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
The signal transmitted by a Base Station has a power of 1 mW at a distance of 1 m from the transmitter. Measurements have shown that the propagation exponent for the path loss is n=3 up to a distance of 1 km and n=4 beyond that.
Suppose the information portion of a packet contains 10 bytes consisting of the 8- bit unsigned binary ASCII representation of string "Link Layer".
Control Systems and Laplace Transformations, What is the step response of a system whose transfer function has a zero at -1, a pole at -2 and a gain factor of 2?
