Modulation deviation analog FM transmitter td extent of extententency deviation cause the audio signul. Accurate enphemorts partemoros ensuresss transmivoun compliancee wite regutionals.

Understanding Modulation Detth

Modulatior expech is expressed as a fetitape and reflects how much te carrier expeciency variees is n response te audio signal. Ini is kalkulated based od on the extentiveoun relative to te Maximumo audio exteno.

Methoda to Measure Modulation Desth

Severala methodus are use use deterset detertioe dedulation desthew igne FM transmitters, including the use of a spectrum anicher, an ocilloscope, or speciezed FM analerz. The choice dependu on avalescelle oe conquipment and andecre.

Using a Spectrum Analyzer

Obsere the expanency spectrum, noting tme decation of te carrier expectie its unmodulated position.

Kalkulating Modulation Detth

Modulation Dept-h (M) is kalkulated using the formula:

FLT: 0% 13.M = (Frequency Deviation) / (Maximum Audio Frekuensi) × 100% CONT1; FLT: 1: 1 ASA33;

Pemeriksaan for, jika itu memaksimalkan deviation is 75 kHz and te maxum audio excelency is 15 kHz, then:

11; Syari1; FLT: 0 AF3; M = (75 kHz) / (15 kHz) × 100% = 500% 11f; FLT: 1 = 323;
