what is the theoretical maximum signaling rate for a channel with the above frequency distribution? [6 points] (b) what is the theoretical maximum bit rate for this channel if a phase- amplitude modulated signal with 64 levels is transmitted over the channel? [6 points] (c) what is the actual maximum bit rate if the signal to noise (s/n) ratio for this channel is 33.111 db?

Answers

Answer 1

On a noiseless 3-kHz channel, binary signals cannot be carried faster than 6000 bps (= 2 x 3000 log2 2).

Once Nyquist understood what we were discussing, he offered a simple equation to calculate the Maximum Data Rate (MDR) of a noiseless channel. L represents the signal's level or condition, and MDR is computed as 2 * Bandwidth * Log2L. Any channel has a defined signal-to-noise ratio at a given temperature. SNR = (Power of signal) / is hence directly proportional to the channel capacity (power of noise). For example, 10 * log10(1000) = 30 dB is a common formula for a signal-to-noise ratio of 1000. a frequency that, if the data supported it, would be the theoretical distribution law frequency rather than the observed frequencies.

What is fsm?

A finite-state machine (FSM), sometimes known as a finite automaton (FSA, plural: automata), or simply a state machine, is a mathematical model of computation. It is an abstract machine that can only be in one of a finite set of states at any one moment. In response to some inputs, the FSM can transition from one state to another; this transition is referred to as a transition. An FSM is defined by a set of states, an initial state, and the inputs that cause each transition. There are two kinds of finite-state machines: deterministic finite-state machines and non-deterministic finite-state machines. A deterministic finite-state machine can be built in the same way as any non-deterministic one.

a cylindrical specimen of some metal alloy 7.0 mm in diameter is stressed in tension. a force of 5270 n produces an elastic reduction in specimen diameter of 0.0049 mm. calculate the elastic modulus (in gpa) of this material if its poisson's ratio is 0.35. enter your answer in accordance to the question statement gpa

Answers

The substance can affect the modulus of elasticity. For instance, the elastic modulus of concrete is about 30 GPa, but the elastic modulus of steel is about 200 GPa (29,000,000 psi) (4,350,000 psi).

Elasticity modulus for aluminum is 69 GPa. The elastic modulus is the slope of the Stress-Strain Curve prior to the onset of plastic deformation. The modulus line's slope is influenced by the atomic composition of the metal. The bulk of the atomic unit cell of steels is composed of nine iron atoms, one in each of the cube's four corners and one in the center. Elastic modulus, commonly known as the modulus of elasticity, is a measure of a material's resistance to undergoing elastic deformation when a load is applied.
