Question-1) A signal with a bandwidth of 14 MHz is first passed through a low filter with a cut-off frequency of S MHz. Then the signal is sampled using the minimum sampling frequency required and each sample is coded with 8 bits. Since the minimum signal to noise ratio is used to make the efficiency of this communication channel 4 bit /s /Hz, how many MHz should the bandwidth of the channel that this signal can transmit be at least? NOTE: If the information in the text and the photo is different, please solve the question using the information given in the photo. Help me please... Thank you so muc

Soru
1-)
Bant genişliği 14 MHz olan bir işaret önce kesim frekansı 5 MHz olan bir alçak filtreden geçirilmektedir. Daha sonra gerekli olan
minimum örnekleme frekansı kullanılarak işaret örneklenip,her bir örnek 8 bitle kodlanmaktadır. Bu haberleşme kanalının etkinliğini 4
bit/s/Hz yapacak minimum işaret gürültü oranı kullanıldığına göre, bu işaretin iletebileceği kanalın Bant genişliği en az kaç MHz
olmalıdır?
(Not: Virgülden sonra 2 basamak giriniz. Doğru cevabın ± %5 sınırında kalanı doğru cevap olarak kabul edilecektir.)
