SNR is defined as the signal power over noise power. For an AWGN with PSD N_0, the noise power is WN_0. So:
SNR=P/(W\,N_0)=(P/W)/N_0=PT_b/N_0=E_b/N_0,
PT_b=E_b, and W~1/T_b for **rectangular** **pulse** signal.

Time shifted signals are very important in the analysis of LTI (linear time invariant) systems and in DSP. Usually you can decompose a complicated signal into basic time shifted signals.

The duty cycle is defined as the ratio between the **pulse** duration and the period of a **rectangular** waveform
In a monostable you only have the duration of the **pulse** but not the period so no duty cycle can be calculated.
If for any reason the monostable is part of a bigger circuit and is trig

This shape should be split between the transmitter and receiver. This split makes square root raised cosine filters at each end.
