DigiAna is the definitive solution for Analog TV signal modulation in the Digiana modulator for analog TV signals. For better stability, DigiAna is able to use of advanced digital processing techniques, solving analog circuit’s implementation impossibilities. By using FIR digital filters, for better spectra and group delay mask, we are able to provide large advantage over SAW filters. Automatic switching when video signal is absent allows transmitter automatic shut-off. DigiAna modulators are designed to deliver audio and video carriers for combined amplification TV transmitters. For better stability, may use the transmitter time base. May also use GPS for sincronization. There is a possibility to equalize or compensate video linear distortions, such as; frequency response and group delay, and video non-linear distortions, such as: differential gain, differential phase, sync compression, and sync stretch as well.
