WebDigital Down Conversion is a technique that takes a band limited high sample rate digitised signal, mixes the signal to a lower frequency and reduces the sample rate while retaining all the information. ... A Digital Down Converter is basically complex mixer, shifting the frequency band of interest to baseband. Webmixer, so that no down-converted image is allowed to be generated by the mixer. Since the desired and image signals are always sepa-rated in frequency by twice the IF frequency, the IF frequency must be high enough to allow the preselector in front of the mixer to block the image, but still allow the desired if signal to enter the mixer. cheryl chou singapore https://preferredpainc.net
