Usually, to highlight the Ts dynamics, a low-pass filter is designed, and to highlight the T1 dynamics, a high-pass filter is designed.
This is implemented through a low-pass filter and a high-pass filter, designed to minimise both the signal distortion and the signal phase delay.
Audio processing capabilities include powerful dynamics and effects, such as a high-pass filter, gate, compressor/limiter, 3-band EQ, delay and the ability to select audio-follows-video channels.
Figure 9 shows that responses of proposed VDBA based filters such as Low-Pass Filter (LPF), High-Pass Filter (HPF), Band-Pass Filter (BPF), and Band-Reject Filter (BRF).
At one limiting case, BPF1 is a low-pass filter, and BPF2 is a high-pass filter. Self-pulsation occurs for a fixed EDFA pump power, by reducing the spectral separation between the BPFs, by red-shifting BPF2.
(ii) If the input voltage is applied at node [v.sub.in2] while nodes [v.sub.in1] and [v.sub.in3] are grounded, the noninverting high-pass filter is achieved.

A high-pass filter eliminates the baseline drift, which is caused by breathing and physical movement.
The high-pass filter was set to 2 kHz rather than 500 Hz to avoid recording composite potentials because the 37-mm CNE had a larger recording area than the SFE (2).
