Statements in connection to Op-Amp applications are : A. If we use a square wave generator followed by integrator circuit we get a triangular wave at the output B. The logarithmic amplifier called a log-amplifier or a logger, is basically a current to voltage converter. C. D. If we use a square wave generator followed by a clipping circuit then we get a saw-tooth wave generator. Choose the correct answer from the options given below:
is a first order high pass filter with voltage follower
A & B only
Let's analyze each statement provided and determine whether they are true or false:
- Statement A: "If we use a square wave generator followed by an integrator circuit, we get a triangular wave at the output."
- An integrator circuit integrates the input voltage over time. For a square wave input, the output of an ideal integrator is a triangular wave. This is a known application of an integrator in op-amp circuits.
- Statement B: "The logarithmic amplifier called a log-amplifier or a logger, is basically a current to voltage converter."
- A log amplifier provides an output voltage proportional to the logarithm of the input current or voltage. The statement correctly describes a log amplifier as a current-to-voltage converter, which is one of its configurations.
- Statement C: " is a first-order high-pass filter with a voltage follower."
- The circuit in the image is a common representation of a first-order high-pass filter. However, without additional details, the specific use of a voltage follower is not apparent just from the image provided. More context would be needed to evaluate the accuracy of this claim.
- Statement D: "If we use a square wave generator followed by a clipping circuit, then we get a saw-tooth wave generator."
- A clipping circuit generally limits the voltage of the waveform to a certain level; it does not inherently produce a saw-tooth wave from a square wave.
Based on the analysis above, the statements that are definitely true are A and B.
Therefore, the correct answer is:
A & B only
