manufacturer:linear description:the value of c should by greater than 15pf to prevent stray capacitance effects introducing errors and distortion of the demodulation s-curve, but the use of very large capacitances with small inductance values will lower the impedance of the tuned circuit at the required q value, reducing the drive level to the demodulator and thereby restricting the video output available. once suitable l and c values have been determined, the working q for the quadrature circuit should be set, the q value determining the video output level and bandwidth. video output is proportional to q whereas video bandwidth is inversely proportional. the effect of q variations on video bandwidth and amplitude can be determined from table 1 and the graphs in fig.5. a value for total damping resistor value to obtain the required q can be calculated from: |
