A unity feedback system has the loop transfer function
\(L(s) = G_{c}(s) G(s) = 10K/[s(s+b)] \)
Determine the relationship between the steady-state error to a ramp input and the gain K and system parameter b. For what values of K and b can we guarantee that the magnitude of the steady-state error to a ramp input is less than 0.1?
How a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice.
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
A digital communications system is being designed with the goal of transmitting 32 kbits/s over a channel having a bandwidth of 8 kHz. Determine (a) the number of encoding levels required and (b) the minimum signal-to-noise ratio required in the c..
Two coupled coils have self-inductances L1 = 50 mH and L2 = 200 mH, and a coefficient of coupling k = 0.5. If coil 2 has 1000 turns, and I1 = 5Sin (400t) (i.e. the phasor current is 5? -90° A). Find the voltage at coil 2 and the flux through coil ..
Design an RC low-pass filter with a cutoff frequency at 2kHz, using a capacitor of \(0.1\mu F\) A. Show a circuit diagram and your calculations in obtaining R B. Make as sketch of the absolute value of the input impedence
The ATSC broadcast television system used in the US transmits video signals at an average rate of 18.34 Mbps and employs 8-VSB modulation.
very useful not only in obtaining the rectangular and polar forms of complex numbers
Explain the process of processor development
What should be the filter's passband cut-off frequency?(DSP Question).
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?
CDMA is a multiple access technique to allow multiple users to share the same bandwidth, based on the orthogonality of their spreading codes. CDMA is a descendent of the direct sequence spread spectrum (DSSS) technology designed for antijam (AJ).
A painter is standing on a work platform that is 27 feet above ground level. For fall protection, the worker''s safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above..
