... from a 4.3 V to 60 V supply voltage. It integrates a 155 mΩ (typical) high-side MOSFET, and is capable of delivering up to 1 A DC load current with exceptional efficiency and thermal performance in a very small solution size. The operating current is typically 40 μA under no load condition (not swit ...

...  Since the motor is at full voltage during the ON pulse, the motor runs at full torque during the ON pulse.  A 25% duty cycle reduces the power applied to the motor close to 25%, yet the speed may not be reduced to 25% of the maximum speed.  A PWM signal is at a fixed frequency. A very low PWM fr ...

Heterodyne



Heterodyning is a radio signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden, in which new frequencies are created by combining or mixing two frequencies. Heterodyning is used to shift one frequency range into another, new one, and is also involved in the processes of modulation and demodulation. The two frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a mixer. In the most common application, two signals at frequencies f1 and f2 are mixed, creating two new signals, one at the sum f1 + f2 of the two frequencies, and the other at the difference f1 − f2. These new frequencies are called heterodynes. Typically only one of the new frequencies is desired, and the other signal is filtered out of the output of the mixer. Heterodynes are related to the phenomenon of ""beats"" in acoustics.A major application of the heterodyne process is in the superheterodyne radio receiver circuit, which is used in virtually all modern radio receivers.
