5.15. TN_GEN: Tone Generation Template

The TN_GEN data structure contains parameters for the Tone Generation Template.

5.15.1. TN_GEN Overview

The tone generation template defines the frequency, amplitude, and duration of a single or dual frequency tone to be played. You can use the convenience function dx_bldtngen( ) to set up the structure for the user-defined tone.

Use dx_playtone( ) to play the tone.

5.15.2. TN_GEN Definition

The typedef for the structure is as follows:

    typedef struct {

       unsigned short tg_dflag;  /* Dual Tone - 1, Single Tone - 0 */

       unsigned short tg_freq1;  /* Frequency for Tone 1 (HZ)      */

       unsigned short tg_freq2;  /* Frequency for Tone 2 (HZ)      */

       short          tg_ampl1;  /* Amplitude for Tone 1 (dB)      */

       short          tg_ampl2;  /* Amplitude for Tone 2 (dB)      */

       short          tg_dur;    /* Duration of the Generated Tone */

                                 /*  Units = 10ms          */

    } TN_GEN;




5.15.3. TN_GEN Parameters

Parameter	Description
tg_dflag	Tone Generation Dual Tone Flag: Flag indicating single or dual tone definition. If single, the values in tg_freq2 and tg_ampl2 will be ignored.
	TN_SINGLE	single tone
	TN_DUAL	dual tone
tg_freq1	Specifies the frequency for tone 1 in Hz (range 200 to 2000 Hz).
tg_freq2	Specifies the frequency for tone 2 in Hz (range 200 to 2000 Hz).
tg_ampl1	Specifies the amplitude for tone 1 in dB (range -40 to 0 dB).
tg_ampl2	Specifies the amplitude for tone 2 in dB (range -40 to 0 dB).
tg_dur	Specifies the duration of the tone in 10 ms units (-1 = infinite duration).
