What is the disadvantages of digital processing?
Processor speed is limited. Develop quantization and round-off errors. Systems and processing is more complex. A higher bandwidth is required for data communication in comparison to analog transmission of an equivalent information.
What are the advantages of the digital system Mcq?
The advantages of digital electronics are more reliable, accuracy is high, easy to design, flexibility is high, higher transmission rate, and more secure.
What are the disadvantages of increasing the order of filter?
The main disadvantage is the complexity. As the order increases the complexity of the filter also increases. This means costlier circuit in production and design and further maintenance. Simply put, Order of the filter means the maximum number of delay elements used in the filter circuit.
What is the disadvantage of higher order filter?
10. State the disadvantage of using higher order filters? Explanation: Although higher order filter than necessary gives a better stop band response, the higher order type is more complex, occupies more space and is more expensive.

Disadvantages:
- The π filter has a loss of power in the inductor.
- It requires higher peak inverse voltage (PIV).
- There is a loss of power in inductor.
- It is costlier and bulky due to use of more filters,.
- It needs larger value of input capacitor.
- It increase peak diode current.
What are the advantages of digital filter?
Advantages of digital filter:
- Many input signals can be filtered by one digital filter without replacing the hardware.
- Digital filter have characteristic like linear phase response.
- The performance of digital filters does not vary with environmental parameter.
- Unlike analog filters; the digital filters are portable.
What is the advantages of using filter?
Advantages of Filters
They are economical or cost-effective. Unlike passive filter circuits, Active Filter Circuits require power supply.
What are the disadvantages of digital communication *?

- Bit error rate or probability of error.
- Require A/D conversion at a high rate.
- It requires more bandwidth as compared to an analog system.
- It needs synchronization in synchronous modulation.
What are the disadvantages of digital communications?
Disadvantages of Digital Communication
- There is high power consumption in digital communication.
- There is a requirement for synchronization in the case of synchronous modulation.
- There is a sampling error.
- The most common limitation of digital communication is that it requires more transmission bandwidth.
What is the disadvantage of digital system over analog system?
Disadvantages of Digital System:
Sampling Error. Digital communications require greater bandwidth. The detection of digital signals requires the communications system to be synchronized.
What are the disadvantages of digital communication Mcq?
4. What are the disadvantages of digital communication? Explanation: Digital communication needs more bandwidth, has higher complexity and little performance degradation occurs during analog to digital conversion and vice versa.
Which one of the following is disadvantage of digital communication in comparison of analog communication?
Disadvantages to using digital signals, including digital signal processing (DSP) and communication systems, include the following: A higher bandwidth is required for digital communication when compared to analog transmission of the same information.
What are the advantages of digital system?
Benefits of Digital over Analog System:
- It is economical and easy to design.
- It is very well suited for both numerical and non-numerical information processing.
- It has high noise immunity.
- It is easy to duplicate similar circuits and complex digital ICs are manufactured with the advent of.
What are the disadvantages of low pass filter?
First Order Low Pass Filter
While this configuration provides good stability to the filter, its main disadvantage is that it has no voltage gain above one. However, although the voltage gain is unity the power gain is very high as its output impedance is much lower than its input impedance.
What are the advantages and disadvantages of Chebyshev filter?
Active vs Passive
| Filter Type | Advantages |
|---|---|
| Chebyshev I | Faster roll off speed than Butterworth. Ripples can be minimised to 0.01dB. |
| Chebyshev II | Faster roll off speed than Butterworth. Ripples can be minimised to 0.01dB. |
| Bessel | Smooth roll off. No ripples. No time delay |
| Elliptic | Fastest roll off speed of all the filters. |
What is the main disadvantage of the Butterworth filter?
However, one main disadvantage of the Butterworth filter is that it achieves this pass band flatness at the expense of a wide transition band as the filter changes from the pass band to the stop band. It also has poor phase characteristics as well.
What are the advantages and disadvantages of band pass filter?
Band Pass Filter is a filter used in signal processing to allow wanted frequency components and to remove the unwanted components from the signals.
Disadvantages
- Active Filters requires power supply.
- Highly sensitive to variations in circuit components.
- They have inherent insertion loss.
What happens when filter order is increased?
So, what happens if order increases, simply the number of delay blocks increases making the filter more complex in design, but making it more and more efficient filter. Simply put, Order of the filter means the maximum number of delay elements used in the filter circuit.
