    Help Gain Calculation

    Hi all! I know voltage gain is given as Vout/Vin...I want to know that whether the values of voltages used for this calculation are rms or peak to peak? Thanks in advance!

    ECG machine Circuit Diagram

    I can't find this IC in simulation software's. u got any idea about a more commonly known Ic as a replacement for INA 326??? Would AD-620A do the trick???

    Help with axial ratio calculation in HFSS

    I want to plot axial ratio vs frequency in HFSS.The problem is that i do not get what ranges of theta n phi to specify for the plot.The 3d and 2d gain plots for my case are attached.Plz help

    Axial ratio plots in HFSSv9 and HFSSv11

    I am trying to workout the axial ratio of my broadband patch antena. My problem is that when i use HFSSv11 to plot the axial ratio it gives seperate lines in the plot for each individual value of theta and phi, while HFSSv9 gives only a single lined plot for theta and phi range.Why HFSSv11 gives...
