Undersampling demodulation of resolver signal
WebCato, currently we have 3 ADCs available that would allow you to undersample a signal above 1 GHz. You can take a look at the ADS5463 (ADS54RF63 has an optimized RF front end giving excellent performance >1GHz), ADS5474 and ADS5400. Here is a quick summary: ADS54 (RF)63: 12bit, 500Msps. ADS5474: 14bit, 400Msps. Websignal which includes the DC level, then finally the objective of C 3 is to block the DC level and we can obtain a pure audio signal at output port. 4.2: Product detector for amplitude …

Next, the signals are sampled by A/D converters (ADC), which produces the digital value of sine and cosine envelope signals given by sin cos s c
WebThe output signals of a resolver contain angular position information, which is modulated by the high-frequency signals with sine and cosine waves. The next step is to demodulate the resolver output signals and determine the angles. In many applications, an integrated circuit (IC), called resolver-to-digital converter (RDC), is used http://site.iugaza.edu.ps/ahafifi/files/Experiment-4.pdf
Web15 Feb 2024 · The experimental results show that, when the central frequency of the beat signal is 200 MHz, its phase signal can be correctly demodulated even using a sampling rate as low as 71 MSa/s. This method can be extended to all existing coherent ϕ-OTDR systems with no or only a few modifications on them. WebUndersampling of Modulated Signals According to the Nyquist sampling theorem, in order to recover a signal via sampling, the sample rate must be greater than or equal to the two …
WebDue to this, the undersampling intensity is practically defined by noise aliasing, taking into account the amount of signal-to-noise ratio (SNR) reduction caused by it considering the application accuracy requirements.
