...of this application note.It is assumed that a filter is designed according to the desired specifications. The desired digital filters may be designed using either standard techniques or using commonly available digital filter design software packages. Finite Impulse Response (FIR) filters have many...

This application note describes the basic issues that need to be addressed in order to implement digital signal processing systems using the PIC16C74 and provides application code modules and examples for DTMF tone generation, a 60 Hz notch filter, and a simple PID compensator for control systems...

...state-variable filter with tunable. cutoff frequency, twin-T notch filter, gyrator notch filter, universal harmonic eliminator. notch comb filter, basic switched-capacitor filters, slew-rate limiter, ECG amplifier with. pacemaker spike detection, "scratch and rumble " filter for ECG, and an intracardiac...

In a classic case of what you don't know can hurt you, design engineers with advanced knowledge of digital electronics are discovering an urgent need to brush up on RF basics when it comes to specifying filters for. wireless devices. Failure to take into account the fundamental aspects of filter...

...or other processing. Note: depending upon requirements, filters may be created using analog or digital techniques. Equiripple Technique: A digital FIR filter design alternative to the window technique that allows designers to achieve a desired frequency response with the fewest number of coefficients...

...in parallel, they can't do as many as a top-notch DSP can. What's more, architectures used in general-purpose processors often require several instructions to perform operations accomplished with just one instruction on a DSP. For.

...spectrum plots. As Figure 6 indicates, the. control system produces an output voltage swing of 90 dB in order to compensate for the peak-notch filter. dynamics. Figure 6: Drive spectrum as reported by control system and measured as an auxiliary input. channel. Conclusion. Your digital shaker control...

...all contained within a single chip. The standard module is fitted with a PIV filter and controls automatic feed-forward velocity and feed-forward acceleration. Other features include a notch and second-order low-pass filter, digital current control, and automatic sinusoidal commutation on all axes...

...the user's dilemma. What, for instance, is notch filtering, and when is it needed? What are the benefits of velocity and acceleration feedforward? Modeling of systems works great until an unforeseen condition is realized. You set up the filter conditions based on measurements taken, then you hope overtime...
