The voltage gain of the non-inverting amplifier can be determined accurately from the feedback resistors Ri and Rf. Calculate the voltage gains for the amplifier of Figure 1 for the Rf values specified, and record them in Table 1. Assemble the circuit of Figure 1 using the 4k7 ( resistor. Set the generator to a 1 kHz sine wave, 100 millivolts peak.

You can then measure the voltage of the output and divide it by the voltage of the signal you sent in. This is the gain. You can convert it to decibels (dB). Obtain the gain in dB at different frequencies. (Say, 1, 2, 3, .., 12 kHz) Task 3: FIR filter implementation.

This practice is fully consistent with power-based decibels, provided the circuit resistance remains constant. However, voltage-based decibels are frequently used to express such quantities as the voltage gain of an amplifier, where the two voltages are measured in different circuits which may have very different resistances.

Gain. The . gain. of an amplifier is the . ratio. of output to input power or amplitude, and is usually measured in . decibels. Example: an audio amplifier with a gain given as 20 dB will have a voltage gain of ten (but a power gain of 100 would only occur in the unlikely event the input and output impedances were identical). Bandwidth. The ...

In other words, the frequency axis is a logarithmic scale and the gain in dB is linear. Using decibels is a typical way of stating gain and is defined as follows: Gain in dB = 20 * log10( gain) = 20 * log10( Vout / Vin ), where Vin and Vout are the input and output voltage, respectively.
