تقريبا كل للقوانين اللي عندنا ف المنهج
==> T = 1 / f
------------------------------------------------------------
Fs : Sampling Frequency (Number of samples per second)
Fmax : Maximum Frequency
q : Number of digital levels in a q-level quantizer (Quantization levels)
v: Number of binary digits to represent each level (Number of bits per sample)
r : Bit rate or signalling rate (Number of bits per second)
------------------------------------------------------------
* Sampling Theorem:
==> Fs ≥ 2 * Fmax
* Nyquist Sampling Theorem:
==> Fs = 2 * Fmax
==> q = 2^v
==> v = log₂(q)
==> r = v * Fs
(Number of bits per second = Number of bits per sample * number of samples per second)
------------------------------------------------------------
==> Band Width (BW)= 0.5 r = 0.5 * v * Fs
------------------------------------------------------------
* Signal Noise Ratio (SNR)
==> SNR = power of signal / Power of Noise
دي هتطلع معاك الناتج بالوات
طب افرض انت عاوز تطلع الناتج ب DB
==> SNR_db= 10 Log 10 (SNR)
==> SNR = 10^(SNR_dB/10)
==> T = 1 / f

بص ي هندسه دلوقتي عندك جميع القوانين اللي عندك في الماده تمام
ده فديو اسمعه هتكون بإذن الله أن مفيش حاجه تجيلك في Scilabe و متعرفش تحلها

دول تقريبا غطوا اغلب اللي عملناه علي packet tracer
ده بيعرفك ازاي تحط IP للجهاز اللي عندك
