What is over-modulating condition in term of amplitude modulation?
When your audio modulating signal is larger than your RF carrier amplitude the peak of the modulated carrier will become flat and a distorted audio signal with flattened peaks will be send out from the detector on the receiver side

What difference between pda and uv detector in hplc?
PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area or height of the peak only at two different wavelengths. But that wavelengths also to be selected before injecting the solution.
What is quasi peak?
Most radiated and conducted limits in electromagnetic compatibility (EMC) testing are based on quasi-peak detection mode. Quasi-peak detectors weigh signals according to their repetition rate, which is a way of measuring their "annoyance factor." They do this by having a charge rate much faster than the discharge rate. Therefore as the repetition rate increases, the quasi-peak detector does not have enough time to discharge as much, resulting in a higher voltage output (response on spectrum analyzer). For continuous wave (CW) signals, the peak and the quasi-peak response are the same. The quasi-peak detector also responds to different amplitude signals in a linear fashion. High amplitude low repetition rate signals could produce the same output as low amplitude high repetition rate signal. Quasi-peak detector readings will always be less than or equal to the peak detection. Because quasi-peak readings are much slower, (by 2 or 3 orders of magnitude compared with peak) it is very common to scan initially with the peak detection first, and then if this is marginal or fails, switch and run the quasi- peak measurement against the limits.

How the efficiency of the detector varies with photon energy?
The efficiency of a detector typically decreases at higher photon energies due to factors such as attenuation and absorption. Different detector materials have different efficiencies for detecting photons of varying energies, so selecting the appropriate detector is crucial for specific applications. In general, detectors may be less efficient at higher photon energies, requiring the use of specialized detectors for accurate measurements.
What are the advantages and disadvantages of automatic heat detector?

What is Difference Between HPLC UV detector Spectrophotometer uv detector?
HPLC UV detector is a component used in high-performance liquid chromatography (HPLC) to monitor eluent absorbance, while a spectrophotometer UV detector is a standalone instrument used to measure the absorption of light at different wavelengths. HPLC UV detectors are specifically tailored for chromatography applications, whereas spectrophotometer UV detectors are more versatile and used for various analytical purposes.
What is the effect of detector temperature on retention time?
Increasing the detector temperature typically decreases retention times by improving peak resolution and reducing peak broadening. However, excessively high detector temperatures can also lead to peak distortion and loss in sensitivity. It is important to find the optimal detector temperature for each specific analysis to achieve accurate and reproducible results.
