.. highpass filters because of their sampled-data nature. Sampled-data systems generate spurious frequencies when the sampling clock of the filter and the input signal mix. These spurious frequencies can include sums and differences of the ...
.. selectable lowpass/bandpass switched-capacitor filter removes the harmonics from a square wave you apply to its inputs. The clock for the MSFS5 is 100 times the input square wave. The 74HC390 and 74HC74 form a divide-by-25 and a ...
.. sharp rolloff, but the passband is too narrow for a typical application. The filter center is 50 times the center-frequency clock and, according to the datasheet, can differ by 0.9% from the calculated value. If we allow the filter pass area ...
.. buffers occupy small footprints on the interface’s PCB (printed-circuit board). For operation at serial-interface clock rates approaching IC 1 ’s 26-MHz maximum, optimize the values of resistors R 1 through R 6 to provide ...
.. circuit by feeding its output back to its reset pin through an RC network. IC 1 outputs a high on the rising edge of the clock by tying its J input high and its K input low. The pushbutton switch connects between the clock input of IC 1 ...
.. side of the I 2 C bus; SDA 1 and SCL 1 are on the slave device’s side. It is fairly easy to optoisolate the clock line because it is unidirectional, from the master to the slave device. A P-channel MOSFET, Q 3 , provides the ...
.. consumer electronics applications, which tend to be lower in frequency and less demanding than typical clock-buffering applications, inexpensive high-speed op amps (~100-MHz bandwidth) can offer an attractive option in ...
.. time constant, a zero shifts into the register. If the low state is short, then a one shifts into the register. The clock and data signals thus combine into one signal. A lowpass filter separates the clock and data signals (Figure ...
.. circuit in the Figure 1, however, can vary the ramp frequency from less than 1 Hz to about 30 kHz just by varying the input clock from 100 Hz to about 6 MHz. The output was measured at a voltage of 5 V peak, but it can be adjusted as well, ...
.. plus ground, the host controller can address the target device and exchange data, whereas SPI requires three wires data, clock, and chip-selection plus ground. Multiple SPI-target devices can share data and clock lines, but each device ...
