కాన్సెప్ట్:

ఇచ్చిన టైమ్ బేస్ ఒక్కో డివిజన్‌కు 1 ms చొప్పున సెట్ చేయబడింది.

అలాగే, 3 పూర్తి చక్రాల కోసం, ఇచ్చిన సైనూసోయిడల్ సిగ్నల్ ఆరు క్షితిజ సమాంతర విభజనలను ఆక్రమిస్తుంది

ఒక చక్రంలో క్షితిజ సమాంతర విభజనల సంఖ్య 2

సైనూసోయిడల్ ఫంక్షన్ యొక్క కాల వ్యవధి \(2\times1\) ms

సిగ్నల్ ఫ్రీక్వెన్సీ =1/T=500 Hz
