Why ripple carry adder is used?
A ripple carry adder needs a much less complicated circuit, than other adder topologies.
What are the disadvantages of ripple carry adder?
time delay
What is the effect of the filter capacitor on the output wave shape of the rectifier?
The larger the cap the smaller the ripple at the power supplies output. It smooths the rectifiers output waveform.
What you do to obtain perfect dc output with no ripple?
This can only be done using a voltage regulator.
Are ripple carry adders and binary parallel adders same?
Yes and no. The ripple carry adder is one type of parallel adder. Other parallel adder types include the pipelined parallel adder and the carry look-ahead adderamongst others.

What is role of CD4020 IC?
CD4020 is CMOS 14-Stage Ripple-Carry Binary Counter/Divider

What is ripple voltage in 12 volt power supply?
A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
What is ripple factor?
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...
What you do to obtain perfect dc output with no ripple?
This can only be done using a voltage regulator.
What are the different ripple removing circuit which one is better and why?
1.control circuit is used for removing ripple 2.analog circuits are also used with TPS84259 negative output voltage power module to reduce the ripple

What is diode ripple?
In a switching DC-DC voltage converter, the oscillatory nature of the switching circuit generates a small "ripple" effect in the output voltage which is supposed to be minimized via careful design of the overall circuit. The output current of this type of converter typically flows through a diode into the rest of the system. The voltage measured at the cathode of this diode will exhibit the aforementioned ripple.
Why do you use look ahead carry adder?
You use a look ahead carry adder to reduce the propagation delay effects caused by the ripple carry that would otherwise be used. With ripple carry, each stage is dependent on the preceding stage, and this is cumulative. With look ahead carry, the carries are computed in parallel, speeding up the overall process.
Advantages of carry look ahead adder?

With ripple carry, each stage is dependent on the preceding stage, and this is cumulative. With look ahead carry, the carries are computed in parallel, speeding up the overall process.
