Flux Density Received Power
This app prompts the user to enter the distance from the satellite to earth in km, the radiated power from the satellite in Watts and the gain in dB i...
SCPC-FM voice S N ratio
This app will determine the S/N for FM voice when the user enters the baseband maximum frequency and the RF channel bandwidth in kHz, the de-emphasis ...
NTSC S N Ratio
For a standard NTSC satellite signal enter baseband video bandwidth (BBV BW) in MHz, the the RF bandwidth (RF BW) of the signal transmitted over the s...
System Noise Temperature
This is the noise model of a receiving antenna, where all of the noisy units have been replaced by one noiseless amplifier with a single noise source ...
Basic Plane Wave Parameters
User enters frequency in GHz, Er & Ur, pushes the "Calculate" button and this app calculates phase velocity, wavelength and impedance. As an example, ...
Astable 555 Timer
Adding a second resistor Rb to the 555 timer and connecting the trigger input to the threshold input causes the timer to self-trigger and run as a mul...
Chebyshev Filter app
This app prompts the user the user for Amax (p-p maximum variation in the pass band) in dB, Amin (minimum response attenuation), Wc (upper edge of the...
Inverse Chebyshev LP Filter
This app is used to determine the ripple factor (e) and the order (n) of the inverse Chebyshev response when the user enters the maximum passband atte...
ECM J S ratio SOJ
For ECM, this app is to calculate the J/S ratio for the stand-off jammer (SOJ) situation. In this case, the jammer is at a different location than the...
