High Duty Cycle to Low Duty Cycle: Echolocation Behaviour of the Hipposiderid Bat Coelops frithii

Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect fluttering targets in cluttered environments. HDC echolocation is found only in the families Rhinolophidae and Hipposideridae in the Old World...

Calculation of the Duty Cycle for BECA

Consumption of energy is one of the major problems in wireless sensor network, as sensor nodes driven on battery power. Therefore, it is intended to minimize the power consumption by putting the wireless interface of the sensor nodes in low power sleep mode. Wireless sensor networks constructed with hundreds and thousands of wireless sensor nodes and they deployed to solve different problems of...

Duty Cycle Adjusting Circuit for Clock Signals

A duty cycle control circuit for clock signals is presented. The proposed circuit uses a rising edge detector to generate one shot output signals which have the same frequency of the input clock signal. A pulse width controllable monostable multivibrator converts the one shot signals into rectangular pulses. By the feedback control voltage from an operational amplifier, the pulse width of gener...
