Pulsed strain gauge topologies

An apparatus, comprising:

• a platform having a first corner, a second corner, a third corner, and a fourth corner;
• a first weight sensor assembly located at the first corner, comprising:
• first full-bridge load cell (FBLC) that receives first excitation pulses during a first state period of a duty cycle;
• first sample and hold (S/H) circuitry connected to the first FBLC that holds first analog measurement signals from the first FBLC;
• first filtering circuitry connected to the first S/H circuitry that processes the first analog measurement signals and produces a first DC level signal;
• and
• first amplification system connected to the first filtering circuitry that amplifies the first DC level signal;
• a second weight sensor assembly located at the second corner, comprising:
• second full-bridge load cell (FBLC) that receives second excitation pulses during a second state period of the duty cycle;
• second sample and hold (S/H) circuitry connected to the second FBLC that holds second analog measurement signals from the second FBLC;
