An antilog is the result of raising the base being used to the logarithm given or calculated. Put another way, it “undoes” what calculating the logarithm of a number does and simply returns that number. … “Antilog” can also be written logb–1 or just log–1 where base 10 is implied by default.
Why do we use antilog in calculator?
An antilog is the reverse of logarithm, found by raising a logarithm to its base. For example, the antilog of y = log10(5) is 10y = 5. The natural logarithm is useful in calculating the amount of time needed to reach a certain level of growth, if, for y = ln(x), y = time and x = value being grown.
Is antilog the same as inverse log?
An antilogarithm (antilog) is the inverse of the log function. The natural log function is base e, which rounds to 2.72. The anti-natural log function is ex.
Is Antilog same as the exponential function?
Antilogs are just another term for exponents, and exponents are the inverse of logarithms. … So now you know that antilogs are the same thing as exponents, and that exponents are just the inverse of logarithmic functions.
What is Antilog amplifier?
An anti-logarithmic amplifier, or an anti-log amplifier, is an electronic circuit that produces an output that is proportional to the anti-logarithm of the applied input. … In the circuit shown above, the non-inverting input terminal of the op-amp is connected to ground.
How do you do antilog in Excel?
How to Calculate Antilog in Excel
- Select the first cell where you want the result to be displayed. …
- Type the formula: =10^B2.
- Press the return key.
- This will display the antilog of the value B2 in cell C2.
- Copy this formula to the rest of the cells of column C by dragging down the fill handle.
How do I get rid of antilog?
Procedure to Find the Antilog of a Number
Step 1: Separate the characteristic part and the mantissa part. From the given example, the characteristic part is 2, and the mantissa part is 6452. Step 2: To find a corresponding value of the mantissa part use the antilog table.
How do you take antilog and log?
Logarithmic Laws and Properties
log b x y = p + q = log b x + log b y. The division of the two numbers is the antilog of the difference of logarithm of the two numbers. The base should be the same for both the numbers. a p = x = b q, and a r = b.
How do you convert log to antilog?
To compute the antilog of a number y, you must raise the logarithm base b (usually 10, sometimes the constant e) to the power that will generate the number y. Where x is the exponent and y is the antilog value. For instance, if we take this equation, log(5) = x, its antilog will be 10x = 5.
What is the disadvantage of log antilog amplifier?
What is the disadvantage of log-antilog multiplier? Explanation: Log amplifier requires the input and reference voltage to be of the same polarity. This restricts log-antilog multiplier to one quadrant operation. … Explanation: In an ideal frequency doubler, same frequency is applied to both inputs.
What is the most important rule of amplifier?
An ideal amplifier has infinite input impedance, zero output impedance, and a fixed gain at all frequencies. An ideal op amp has infinite input impedance and zero output impedance, but has infinite gain.
Which of the following is the disadvantage of op amp?
The disadvantage of the Op-amp is designed for low-power operation only, not suitable for high output, and requires passive components. The applications of the op-amp are voltage comparator, Schmitt trigger, triangle wave oscillator, differentiator, and integrator. 1).
