Hello, I´m using Visual Analog. I have a Continuos wave dopler ultrasound system.The frequency of the transmitter fo is 5 MHz. My input comes from the receiver. The input signal is a Doppler signal , so once i have this signal in visual analog, i want to create a quadrature demodulator. I know that there are some blocks concerning I &Q, but i don´t know how to use them properly to create the quadrature demodulator.
Thank you very much.
