Figure D$3: Sampling Function SIN(X)/X Pulse Formula and Waveform

Constants

k0 indicates the frequency of the sine wave; k1 indicates the peak location

 

of the pulse.

 

 

 

 

Description

In general, this waveform is expressed by the following formula:

 

V￿t￿/ +/

sin/ ￿2pft￿

 

 

 

 

2pft

 

This is the impulse response for the ideal low pass filter for the frequency

 

bandwidth f. At least 326 periods are required in order to use a vertical

 

resolution of 12 bits.

 

 

Settings

Waveform points: 4000
