Return to Zero

A type of digital signal where 1's and 0's are pulses of opposite polarity, but between each bit the line returns to the zero (ground) state. It is rather inefficient in terms of bandwidth/data rate, as each bit transmitted uses two baud (i.e. state changes).

What are the difference between carrier signal modulating signal modulated signal baseband and passband?

carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)

Bandwidth of digital signal is infinite?

A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.


What is the use of connecting an integrator in delta modulation?

integrator converts the quantised signal to saw tooth signal which then compared with the present signal and error signal is generated,and error signal is quantised and the process continues


Unit step signal is energy or power signal?

The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.

What is the digital to digital signal encoding technique?

The digital encoding techniques are of two types--Polar and Bipolar. The polar encoding are--RZ(Return to Zero), NRZ (No RZ) , Manchester and Differential Manchester. Bipolar encoding are--AMI ( Alternate Mark Inversion) and BnZS ( Bipolar n Zero Substitution).

If z is the midpoint of RT what are x RZ and RT?

If z is the midpoint of RT, it means that RZ is equal in length to ZT. Therefore, RZ = ZT. Additionally, the segment RT is twice the length of RZ (or ZT) since Z is the midpoint. Therefore, RT = 2 * RZ.

Ra is Indian standard whereas Rz is DIN standard


How can the Rz value measure high even if the surface finish is good?

Because, there are two types of RZ value- shortwave & longwave. A High Longwave RZ value will be less smooth than a high shortwave RZ value, because in shortwave, even though the RZ value is high, the undulations are very close together, and so will appear smooth when measured over a long or short area. A High RZ longwave surface appears less smooth, as the undulations occur over a longer area, and so will have more effect with relation to how smooth the surface is. RZ measures only the height of the surface descrepancy at any given point, its not concerned with the frequency of that descrepancy over any distance of the surface-this is how RZ value can be high, but surface finish appears smooth- Its a High RZ, short wavelength surface.
