What is the difference between a discrete and continuous system?

Serjik [45]

Answer:Discrete system are those system which change the state at the discrete point of time and continuous system are those which have state change at continuous period of time.

Explanation:

The major difference between discrete and continuous system is that, discrete system has state change over a discontinuous time period whereas the change of state in continuous system is over a continuous time period .
Variations can be found in the discrete system signal but in continuous system variation cannot be found input and output signal.
Example:-

Discrete system:-employees reporting at office at different time like

9:10am, 9:15am etc

<u> Continuous system</u>:-the water flow over a dam in particular quantity

An incoming signal is at a frequency of 500kHz. This signal needs to be acquired and all other signals attenuated. Design a pass

Finger [1]

Answer:

C_h = 0.166 nF

C_L = 0.153 nF

Explanation:

Given:

- Ideal frequency f_o = 500 KHz

- Bandwidth of frequency BW = 40 KHz

- The resistance identical to both low and high pass filter = 2 Kohms

Find:

Design a passive band-pass filter to do this by cascading a low and high pass filter.

Solution:

- First determine the cut-off frequencies f_c for each filter:

f_c,L for High pass filter:

f_c,L = f_o - BW/2 = 500 - 40/2

f_c,L = 480 KHz

f_c,h for Low pass filter:

f_c,h = f_o + BW/2 = 500 + 40/2

f_c,h = 520 KHz

- Now use the design formula for R-C circuit for each filter:

General design formula:

f_c = 1 /2*pi*R*C_i

C,h for High pass filter:

C_h = 1 /2*pi*R*f_c,L

C_h = 1 /2*pi*2000*480,000

C_h = 0.166 nF

C,L for Low pass filter:

C_L = 1 /2*pi*R*f_c,h

C_L = 1 /2*pi*2000*520,000

C_L = 0.153 nF

Radioactive wastes are temporarily stored in a spherical container, the center of which is buried a distance of 10 m below the e

BabaBlast [244]

Answer: 76.3 ° C

Explanation:

Outside Distance = 10 m

Outside diameter, d = 2.2 m

R=D/2 = 2.2/2= 1.1 m

inner radius, Rs = = 1.1 m

Surface Temperature Ts = 20°C

Given that the thermal conductivity of soil, K = 0.52 W/mK

We can find the outside temperature of the container by finding the thermal temperature of conductor, T, and then summing up with the surface temperature

That is (T + Ts)

we know amount of heat, Q is given by :

Q = [(T-Ts) / (R- Rs)/4πKRRs

500 = T-20 [4π×0.52×1.1×10] / (10-1.1)

500= T-20 (71.88/8.9)

500 = T-20 (8.08)

500 = 8.08T - 161.6

8.08T = 500 + 161.6

8.08T = 661.6

T = 76.33 ° C
