The waveform attached shows sine wave. But my requirement is the waveform as shown in post 1.Pulse parametrics :
Continuous -
1) You want period individual sine variable ?
2) Modulation period, overall frame width, variable ?
Triggered -
1) Single pulse or N pulses, you control N ?
An example, substitute mentally your sinc pulse for the sines in pic (the 4 sines is the frame)

2) You want period individual sine variable ?
3) Modulation period, overall frame width, variable ?
Timing accuracy for both continuous and tiggered, for the individual sine and whole frame ? +/- 50%, +/- 1%.........?

Answers to the questions ?The waveform attached shows sine wave. But my requirement is the waveform as shown in post 1.
Is there a general reference regarding this. Relation between the pulse width of square wave and the L and C components etc. Because once the design equation is known I can modifying based on available component for initial trial.
There should be something simpler, in my opinion. The power level will be in 200-300W. At high voltages of 400-500V. The frequency frequency between the rise and fall is around 55kHz
As a basic trial simulation, I tried Square wave with LC filter in LTspice
I'm basically illustrating my previous comment that the requested waveform is a bandpass pulse response (or a synthesized waveform, multiplying sine with gauss pulse). I found that a filter with "soft" characteristic, specifically Bessel gives best results, that 30 % relative bandwidth is roughly giving the intended shape and that third order (three complex pole pairs) produces already a useful waveform, although not exactly symmetric.I hate to tread on FvM's delightful and appropriate solution, it's really nice and simple (but I'll bet it's not 'simple' to calculate component values) and what you were asking for. Great!
