Abstarct: One of the most important components of health monitoring is the measurement of blood pressure. Blood pressure is measured through scor barometers, cuffs, arterial measurement, and recently oscillator barometers. Unconventional nature, disability in mobile monitoring applications, inaccuracies in movement, and the need for pre-measurement calibration and calibration are all among the problems of these tools. In a new study, with the analysis of photoplethysmogram (PPG) signals and electrocardiogram (ECG) signals, and taking into account the condition of individuals, a new parameter called pulse transit time (PTT) is introduced, which is a potential parameter for estimating uncontrolled hypertension. The common problem is the recording of biological signals, noise, and interference of electrical waves, which causes the signal to signal failure or its analysis. Therefore, it is necessary to eliminate the effect of noise in these signals. In this research, the bank signals are used to remove noise from vital signals. By using bank filters and by breaking down at three levels, the SNRs increase vital signals and measure blood pressure with these signals more accurately. This method has been applied to ECG and PPG signals with noise and acceptable results in measuring blood pressure.
