I found these interesting DSP Design Tools from Lowegian International Corporation.
1. ScopeFIR is a comprehensive tool for designing, analyzing, and modifying complex Finite Impulse Response (FIR) filters. It designs FIR filters via the Parks-McClellan algorithm, as well as all other major FIR filter design methods.
2. ScopeIIR is a comprehensive tool for designing, analyzing, and implementing Infinite Impulse Response (IIR) filters. It can design filters from Butterworth, Chebyshev, and Elliptic prototypes, and lets you to adjust the resulting poles and zeros to fine-tune your IIR filter design.
3. ScopeDSP is a comprehensive tool for analyzing sampled-data signals. It transforms between the time domain and frequency domains using an efficient arbitrary-N Fast Fourier Transform (FFT). Its powerful analysis features provide plots and statistics for both the time and frequency domains.
This is a great introductory video on FIR filters:
