an adiabatic throttling process for R-134a takes saturated liquid at 800 kPa entering, and drops the pressure to 280 kPa (constant specific enthalpy). Determine the quality exiting and the specific entropy change for the throttling process.
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
What is the maximum symbol rate that the twisted pair line can carry without ISI? 256-QAM modulation is used on the link. How many bits are conveyed by each symbol?
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
An infinitely long line charge (Pl= 21 PI nC/m) lies along the Z-axis. An infinte area sheet charge PS= 3nC/m^2 lies in the X-Z plane at a distance Y =10 m. a) Using Gauss' law find the field E due to the line charge.
Important information about Digital signal processing, (a) Design a lowpass FIR digital filter using "remez" routime in Matlab for the following specifications:
For a given lithium ion battery, it can supply 0.85 ampere-hours, or 850 (mAh) with a constant output voltage of 3.6 (V). How much energy is stored in this lithium ion battery. How much energy is imparted to an electron that flows
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
Using the Nth order term only of the transfer polynomial, find the Nth order relationship for the Nth order products.
Design a logic circuit to produce a high output only if the input, represented by a 4-bit binary number, is greater than twelve or less than three. Implement a minimized circuit using only NAND gates.
Digital Communications, Order the following modulation types in terms of spectral efficiency (best to worse) and explain
