How can you avoid aliasing error during sampling when converting an analog signal?
Romashka-Z-Leto [24]

Answer and Explanation:

Aliasing is a distortion in the signal when a continuous signal is converted into digital signal that is ADC process, due to this effect the signal aliases of one another.There will be no aliasing effect if the frequency of the signal will not be higher than the sampling frequency

The another way of avoiding aliasing is to limit the range of the continuous signal.

Saturated liquid-vapor mixture of water, called wet steam, in a steam line at 1500 kPa is throttled to 50 kPa and 100°C. What is
frozen [14]

Answer:

x = 0.944

Explanation:

Steam at outlet is an superheated steam, since T > T_{sat}. From steam tables, the specific enthalpy is:

h_{out}=2682.4\,\frac{kJ}{kg}

The throttle valve is modelled after the First Law of Thermodynamics:

h_{in} = h_{out}

Hence, specific enthalpy at inlet is:

h_{in}=2682.4\,\frac{kJ}{kg}

The quality in the steam line is:

x = \frac{2682.4\,\frac{kJ}{kg}-844.55\,\frac{kJ}{kg}}{2791.0\,\frac{kJ}{kg} - 844.55\,\frac{kJ}{kg} }

x = 0.944

You have measured the force of a hammer hitting a nail by using a new sensor. The result is 60 million dynes is this reasonable
Vesnalui [34]

Answer:

Yes, it is Reasonable.

Explanation:

The problem states that by using a new sensor, the result is 60 million dynes.

Converting the force into Newtons, by using the formula,

1 newton = 10⁵ dynes,

i.e, 1 million dynes = 10 newtons.

we get,

60 million dynes = 60 x 10 newtons = 600 newtons.

The result using a new sensor is reasonable because atmosphere exerts a force of about 10 newtons on us and 600 newtons is just 60 times of it.

Thus 600 N can be applied by the hammer on the nail and it is reasonable.
