We understand that the most important criteria are usually time-to-market and system performance, and we are determined to meet both on every project we pursue, while holding the line on cost. Because of this, our approach is to meld theoretically optimum solutions with efficient real-time implementations (no tinkering, guessing, or trial and error).
About Us
Signal Processing Consultants, Inc. was founded in 1992 to address the needs of companies for custom, high performance, high quality signal processing systems. Since then we have helped numerous clients get products to market which meet price/performance requirements. Every client has renewed our contract for at least one term, some for as many as 10 years.
Bruce L. McKinley, President And Principal Engineer
- Experience in the Wireless/Telecom, Military, Intelligence and Commercial industries.
- More than 3 decades of complete client satisfaction as an independent consultant
- The client’s best interest is always our utmost concern, and we strictly adhere to the IEEE Code of Ethics
